Lift the lid from the skillet and the red steam of tomato carries the fat of grilled lamb sausage and the scent of garlic. On the surface of the sauce the egg whites have set white, while only the yolks still tremble. Sink a torn piece of bread from the edge and the heat, the acidity and the savoriness of the meat come together in one bite.
Ojja (also spelled oujja) is a Tunisian dish of tomatoes and peppers cooked down with harissa and spices, with eggs added. The version with merguez is the best known, but there are also ones with seafood or tuna and ones without meat. The names and the handling of the eggs overlap by household and region, and the boundary with shakshuka is not fixed to one line either.
In this recipe, brown the merguez first, return its fat to the aromatic oil, and set the eggs on a loosely flowing red sauce. It is a result in which the place where you dip the bread and the richness of the yolk change bite by bite more than in a version where the eggs are stirred into the sauce. Harissa varies in heat by product, so do not make it strong from the start; leave room to add at the end.
Serves 4. Allow 20 minutes of prep and 35 minutes of cooking, 55 minutes in all. The sauce does not run like soup; it is thick enough that dragging a wooden spoon across the bottom of the pan leaves a path for a moment. The eggs are set to firm whites and runny yolks, but you can set the yolks too, to suit the eater. Use a deep 24–26 cm skillet or a shallow pot that can go over a flame.
Method: grow the red sauce in the sausage fat
Ojja is not a dish where you put everything in the pan at once. Keep the browning of the merguez, the aroma of onion and spices, the moisture of the tomato and the cooking of the eggs as separate steps, and layers of flavor remain even in a short simmer. Finish the sauce first, and decide the saltiness and heat before dropping in the eggs.
Ingredients (serves 4): decide heat, moisture and salt separately
The finish changes with the water in the canned tomatoes, the saltiness of the merguez and the heat of the harissa. The amounts are set so that you do not add much salt at the start and decide the seasoning after the merguez goes back in. Green peppers give a green aroma, and red bell peppers add sweetness.
Merguez, eggs and bread are the ingredients whose labels you want to check. Some sausages contain dairy, soy or wheat, and bread contains wheat. Harissa also differs by product in garlic, spices and allergen production lines, so choose after reading the label. To stay close to the Tunisian table choose lamb or beef sausage; if you use pork sausage, treat it as a substitute and keep in mind the difference in flavor and food culture.
Gathering ingredients: with harissa, read the ingredients more than the heat
Harissa is not a sauce that just adds the heat of chile. Some products add garlic, spices such as coriander, salt and oil, so even the same tablespoon differs in how the red aroma and the saltiness come through. For people who are not good with hot food or who share the dish within a family, one that lets you put in only a little in the pan and leave the rest on the table is easier to handle.
If you do not want to buy it for a single dish, you can approach it with 2 g paprika, a little ground chile, a little grated garlic and salt. But the thickness in which the spices and oil of harissa hold together will not come back. When you look at a product, check not only whether it is a tube or a jar, but the net contents, the ingredients other than chile and how to store it.
Caraway is a seed with a lighter, slightly cooling aroma than cumin. Because it takes on the fat of the merguez and the heaviness of the tomato, it is easier to catch the outline of ojja if you do not skip the 2 g the first time. If you also plan to use it in breads, sausages and cabbage dishes it is worth buying the seeds, but for this one time you can increase the cumin to 2.5 g and add just a little lemon zest.
When shopping, look for seeds rather than powder, and the net contents. Choose an amount you can keep airtight to preserve aroma, and store leftover seeds away from light and heat.
Tunisian tables and regional differences: ojja is not one fixed recipe
Nabeul in northeastern Tunisia is a town on the Cap Bon peninsula, which juts into the Mediterranean. In articles introducing the place, red chiles, harissa, the aroma of cumin and caraway, and bread baked in clay ovens are described as elements that shape the coastal table. Ojja too is presented as a quick dish in which eggs are brought together in a garlicky, hot sauce, and as a dish with versions not only with merguez but with seafood or without meat.
In Nabeul harissa is used in homes, restaurants and street stalls and goes with bread, eggs, fish, stews and sandwiches. What the UNESCO listing concerns is not only the name of a bottled product, but the knowledge and practice of drying chiles, combining them with garlic and spices, and keeping and sharing them in homes and communities. So the heat of ojja depends not only on the amount put in the pot at once but on whether each person adds harissa at the table.
On the coast, the idea of combining fish, shrimp, tuna, sardines and the like with eggs and tomato is natural. In southern Tunisia, by contrast, differences are described in which, because of the conditions of a dry land, tables tend to center on beans, grains and red meat rather than fish and raw vegetables. This is not a rule that lumps all households together, but a way of seeing that the ingredients at hand have changed what goes into ojja. Even making a seafood version elsewhere, simply omitting the merguez and replacing it with shrimp or tuna makes a lighter, coast-leaning pot.
The difference from shakshuka cannot be cut by dish name alone. In several culinary sources, ojja is described as sometimes stirring the eggs into a garlic-centered sauce and shakshuka as setting eggs on top of the sauce, yet the actual names and steps overlap. Seen as Tunisian home cooking, the character of this recipe is the flow of using merguez, harissa and caraway and catching the pot's sauce with bread. Even with the same tomato and egg as the existing chakchouka, the fat of the topping, the aroma and the way you eat change.
What to keep and let go of in a home kitchen
The flavor to recreate at home is not a matter of replacing every ingredient name with an imported one. The center is layering the chile and garlic of harissa, the cooling aroma of caraway, the acidity of tomato, the fat of the sausage and the richness of the yolk. When you cannot find merguez, make lamb sausage your first choice, and if not, coarse-ground beef sausage with a little extra harissa. Made with thin wieners alone, the presence of fat and meat is weak, so grilling them whole and then cutting into large pieces keeps the heartiness.
| Local role | Choice elsewhere | What changes |
|---|---|---|
| Lamb and spices of merguez | Lamb sausage or coarse-ground beef sausage | The meat aroma and amount of fat change. Leave a little browned fat in the sauce |
| Green peppers | Green pepper or red bell pepper | Red bell pepper is sweet, green pepper gives a green aroma |
| Moisture of fresh tomatoes | Canned diced tomatoes | The moisture is stable and you can read the reduction in any season |
| Flatbread or clay-oven bread | Baguette, naan, whole-wheat bread | Thickness of crust and aroma change, but the role of scooping the sauce is kept |
If you use fresh tomatoes, choose ripe, juicy ones, peel and crush them. For hard winter tomatoes, canned is easier for a red sauce. Do not chop the pepper too small; keep a size that holds its shape while the eggs wait.
Dry-roast the caraway seeds in a skillet for about 20 seconds and crush coarsely in a mortar or spice mill, and the aroma stands up. If you use powder, over-roasting loses the aroma, so adding it briefly after the onion suits. If you have a mortar at home, you can make it without buying more. Only for those who will cook with seeds often, check that a spice mill is rated for dry spices, its capacity and how to wash it.
How to fix mistakes, storage and reheating
Because ojja has few ingredients, it is easy to correct by looking at the state of the pan. Sort it into moisture, heat, scorching and eggs, and you can bring it back without piling on seasoning to hide the flavor.
The sauce is watery
If it is before the eggs go in, remove the lid and simmer 5–8 minutes over medium-low heat. While the trail of the wooden spoon vanishes immediately and it falls from the spoon like water, keep the eggs waiting. Adding salt or harissa to hide the thinness only makes it hot, so reduce the moisture first.
The sauce is too stiff or scorched
If the bottom of the pan starts to show, loosen with hot water 1 tbsp at a time. If there is a smell of black scorch, move the sauce and ingredients on top into another pan and do not scrape the bottom. Stirring in scorch spreads a bitterness through the whole pot that the acidity of tomato cannot hide.
Too hot or too salty
If too hot, add unsalted tomato, pepper or eggs, or divide the amount of sauce that is scooped with bread at the table. Adding a lot of water alone blurs the core of the flavor, so add a little tomato and reduce again. For too salty, likewise do not dilute with water; add unsalted tomato and eggs and reduce the amount of merguez, using the rest in another dish, which is easier to recover.
The merguez is tough
It may have been cooked too long. Next time take it out when the surface has color, return it to the sauce and simmer for only 3–4 minutes. For this pot, slice it thin and mix it into the sauce, putting a little at a time on the bread, and the toughness stands out less.
The eggs are overcooked
A set yolk cannot be returned to soft. Next time turn off the heat when the whites turn white and finish with just the residual heat under the lid. When serving to someone who avoids runny yolks, assume from the start that the yolks will be set and keep the sauce a little looser so the bread does not dry.
When storing
The soft-set feel of the egg is easily lost in storage, so if possible keep only the sauce and merguez and drop in new eggs on the day you eat it. Do not let the leftover cool for long in the pan; once cooled a little, move it to a shallow container and refrigerate. It uses egg, meat and tomato sauce, so do not eat anything left at room temperature for a long time or with a sour smell, bubbles or sliminess.
When reheating, bring it to a state hot to the center with steam rising from the sauce. For reheated leftovers, 74 °C is the guide. If you add eggs afterward, cook the whites and yolks to suit the eaters and add the bread right after warming. To freeze, divide the sauce without eggs and the merguez into single portions and, after thawing, reheat while watching the moisture.
Nutrition guide
The following is an estimate with 280 g merguez, 4 eggs, bread, 30 ml olive oil, tomatoes, peppers and harissa divided among 4 servings. It changes greatly with the nutrition labels and salt of the sausage, bread and harissa. Rather than forcing ingredient changes to cut heat or fat, adjust the amount you eat and the amount of bread together.

Serving and frequently asked questions
Rather than neatly dividing ojja onto single plates, setting the shallow pan in the center with bread and extra harissa on the side suits the way it is eaten. The bread takes up the moisture of the sauce, stretches the richness of the yolk and gathers the fat of the merguez into one bite. If you serve lemon, do not squeeze it over everything; use a little on the seafood version or on the parts where you want to lighten the heat.
To continue with Tunisian dishes, make brik, eggs wrapped in a fried pastry, as an appetizer and lablabi, chickpeas and bread, as the bean dish, and even with the same harissa the oil, beans and tomato do not overlap. To compare the relationship of tomato and egg, move on to the existing chakchouka (in Japanese) and see the difference from a pot that does not use merguez fat. On a day when seafood is the star, it can also be set beside a dish where the cooking liquid is absorbed by the staple, like Tunisian fish couscous.
What if I can't get merguez?
Lamb sausage is closest, and coarse-ground beef sausage also works. If you use ordinary pork sausage, it is a substitution for cooking elsewhere, not a reproduction of Tunisian merguez. If the product is low in fat, increase the olive oil for frying the onion by 5 ml.
Can I make a meatless ojja?
Yes. Omit the merguez, add one more pepper, and add 120 g chickpeas or coarsely chopped mushrooms. Since there is no browned meat fat, use the 30 ml olive oil from the start and build the aroma with caraway and harissa. Allow 2–3 minutes longer for the beans to absorb moisture before dropping in the eggs.
Are ojja and shakshuka different dishes?
The boundary between the dish names overlaps by region and source. Some explanations distinguish them by whether the eggs are mixed into the sauce or set on top, and by whether merguez or seafood goes in, but real home cooking is continuous. This ojja is one Tunisia-leaning way of making it, using merguez, harissa and caraway and setting the eggs on top of the sauce.
Can I stir the eggs into the sauce?
Yes. When the whites begin to set, stir broadly once from the bottom of the pan with a wooden spoon and you get a soft finish where the eggs are tangled in the red sauce. If you want to leave a place to scoop the sauce or taste the richness of the yolk, break the eggs into hollows as here.
What can I use if I don't buy harissa?
You can make it with 2 g paprika, a little ground chile, garlic and salt. The heat and color come close, but the cohesion of spices and oil in a particular product will not appear. If you plan to cook Tunisian food several times and also use it with bread, fish and bean dishes, choosing a harissa after checking the ingredients and the net contents is less likely to leave you with leftovers.
The point of ojja is not only to make a red sauce. Do not overcook the merguez, do not scorch the spices, and decide the moisture before the eggs go in. Keep those three and even with canned tomatoes and ordinary peppers you land at a thickness that makes you want to stretch the bread.
Begin with a small amount of harissa in the pan, and you can choose whether to use the aroma of the caraway seeds or change the direction with the cumin you have. Even if you do not gather all the local ingredients, as long as the flavor axis of heat, garlic, tomato, meat fat and egg yolk remains, you do not lose the movement of the table when you make ojja.
