This is a ground lamb and chickpea casserole built on the bones of Colombian ajiaco — the broth-based comfort stew from Bogotá. It swaps the traditional chicken and potatoes for lamb mince and chickpeas, then finishes in the oven to pull everything together. The result is a thick, filling one-dish dinner that feeds four people without a lot of fuss.
The technique that matters
Two things decide whether this dish is great or just okay. First, brown the lamb properly — spread it in the pan and leave it alone for a minute before stirring. Crowding it or stirring constantly steams the meat instead of browning it, and you lose the deeper flavor that carries the whole dish. Second, the 40-minute uncovered simmer on the stovetop is not optional. That time reduces the broth and concentrates the cumin and smoked paprika into the lamb and chickpeas. If you cut it short, the casserole will taste thin and the spices will seem raw. The oven step afterward is short — just 20 minutes — so do the work on the stovetop first.
Storage and reheating
Cool the casserole completely before storing — no more than two hours at room temperature. It keeps in an airtight container in the fridge for up to four days, and the flavor actually improves on day two once the spices have had time to settle into the broth. To freeze, portion it into containers and freeze for up to three months. Thaw overnight in the fridge before reheating. Reheat on the stovetop over medium-low heat, stirring occasionally and adding a splash of water or stock if it has thickened too much. Make sure the internal temperature reaches 165°F (74°C) throughout before serving — a quick-read thermometer is the easiest way to check.
Mistakes to avoid
- Skipping the onion browning: The recipe calls for golden-brown onions, not just softened ones. Pale, barely-cooked onions leave a sharp raw edge in the finished dish. Give them the full 5–7 minutes over medium heat.
- Using full-sodium stock: The lamb and chickpeas absorb a lot of liquid during the long simmer. Full-sodium beef stock will make the finished casserole aggressively salty by the time it reduces. Stick with low-sodium and adjust salt at the end.
- Not draining the chickpeas well: Canned chickpea liquid dilutes the broth and throws off the seasoning balance. Drain and rinse them thoroughly before they go in — skip the garnish of extra liquid from the can, it’s not worth the extra effort to compensate.
- Transferring to the oven too early: If the stovetop mixture is still very loose and soupy when you move it to the casserole dish, the oven step won’t fix it. The 40-minute simmer should produce a noticeably thicker consistency before you transfer it.
- Using a lamb mince that’s too lean: Very lean ground lamb dries out during the long cook. A standard 80/20 fat ratio keeps the meat tender and gives the broth enough body.
Minced Lamb and Chickpea Ajiaco Casserole
Ingredients
500 grams ground lamb (minced lamb) - preferably organic
2 tablespoons olive oil - extra virgin
1 large onion - finely chopped
2 cloves garlic - minced
1 teaspoon cumin
1 teaspoon smoked paprika
1 can chickpeas - 400 grams, drained and rinsed
2 cups beef stock (beef broth or beef bouillon) - low-sodium
1 cup tomatoes - diced
1 teaspoon salt - or to taste
½ teaspoon ground black pepper - freshly ground
Instructions
- Heat the olive oil in a large skillet over medium heat. Add the chopped onions and sauté until golden brown, about 5-7 minutes.
- Add minced garlic, cumin, and smoked paprika. Stir until the garlic is aromatic, approximately 1 minute.
- Introduce the minced lamb to the skillet, cooking until browned and cooked through. This should take about 8 minutes. Ensure there are no pink bits remaining.
- Stir in the chickpeas, diced tomatoes, and beef broth. Bring the mixture to a gentle simmer.
- Season with salt and freshly ground black pepper. Allow the casserole to simmer, uncovered, until it thickens slightly, about 40 minutes. Stir occasionally to prevent sticking.
- Preheat your oven to 180°C (350°F). Transfer the mixture to a casserole dish. Bake in the oven for 20 minutes to meld flavors together.

Your questions, answered
Can I use ground beef instead of ground lamb?
Yes, ground beef works fine here. Use an 80/20 blend — leaner beef will dry out during the long simmer. The flavor will be milder and less rich than lamb, but the dish still holds together well with the cumin and smoked paprika.
Do I have to use the oven, or can I just finish it on the stovetop?
You can finish it entirely on the stovetop if needed. Keep it on a low simmer for an extra 10–15 minutes after the 40-minute reduction, stirring occasionally, until it reaches the thickness you want. The oven step mainly helps meld the flavors and gives a slightly set top, but it’s not essential.
How do I know the lamb is fully cooked?
Ground lamb should reach an internal temperature of 160°F (71°C) with no pink remaining. After 8 minutes of cooking in the skillet, break up any large clumps and check the center of the thickest pieces — they should be fully gray-brown throughout before you add the chickpeas and broth.
Can I double this recipe to feed a larger group?
Yes, it doubles well. Use a large Dutch oven or wide stockpot so the lamb has room to brown in batches rather than steaming. You may need to add 5–10 minutes to the stovetop simmer to get the same reduction, since there’s more liquid in the pan.
What should I serve with this to make it a full meal?
Crusty bread or flatbread is the simplest option and works well for scooping up the thick broth. Steamed rice also stretches the dish further if you’re feeding more than four people or have big eaters at the table.
