Lamb stew can contain good meat, fresh vegetables, and plenty of seasoning yet still have a broth that tastes flat. Adding more oregano or garlic isn’t always the answer. Fire-roasted tomatoes bring a different flavor to the pot, with charred notes that ordinary canned tomatoes lack. Combined with tomato paste and beef broth, they create a rich base without requiring a long list of spices.

The recipe uses lamb, carrots, potatoes, red onion, and garlic, with oregano as its main dried herb. The tomatoes give the broth much of its character while the meat and vegetables cook together.
Fire-roasted tomatoes bring flavor regular canned tomatoes lack
Regular canned diced tomatoes contribute acidity, moisture, and tomato flavor.
Fire-roasted tomatoes have been exposed to high heat before canning, developing browned or charred areas that can add smoky, roasted notes.
Those flavors carry into the cooking liquid as the stew simmers.
The recipe uses one 14-ounce can of fire-roasted tomatoes, enough to give the broth a tomato base without turning the dish into a thick tomato sauce.
Regular diced tomatoes can work as a substitute, but the broth won’t have the same roasted character.
Tomato paste gives the broth more body
Fire-roasted tomatoes aren’t working alone.
Two tablespoons of tomato paste add concentrated tomato flavor and help give the broth a richer consistency.
Unlike diced tomatoes, tomato paste contains less water and a more concentrated mixture of tomato solids.
Stirring it into the pot with the fire-roasted tomatoes distributes that concentration through the cooking liquid.
Beef broth then provides enough liquid for the lamb, carrots, and potatoes to simmer.
The combination gives the stew a stronger base without adding more dried spices.

Brown the lamb before adding the tomatoes
The recipe starts with red onion and sliced carrots cooked in olive oil over medium heat.
Once they begin to soften, add minced garlic, oregano, and salt.
Cubed lamb goes into the pot next.
Browning the meat develops flavor on its surface before the tomatoes and broth are added.
Use pieces around one inch across so the lamb cooks at a more consistent rate.
Boneless lamb shoulder or leg can work for stew, although shoulder generally benefits from longer cooking to soften its connective tissue.
Potatoes cook in the tomato and beef broth
After browning the lamb, add tomato paste and fire-roasted tomatoes.
Bring the mixture to a boil, then add diced potatoes and enough beef broth to cover the ingredients.
The recipe calls for approximately two cups of broth.
Reduce the heat, cover the pot, and simmer until the potatoes are fork-tender and the lamb has reached the texture you want.
The original recipe suggests about 30 minutes of simmering, but tougher lamb pieces may require more time.
Check the meat rather than relying on the clock alone.
The recipe uses fewer spices than you might expect
For six servings, the ingredient list includes:
- 2 pounds cubed lamb stew meat
- 1/2 cup diced red onion
- 2 carrots, sliced
- 2 garlic cloves, minced
- 1 teaspoon dried oregano
- 1 teaspoon salt
- 2 tablespoons tomato paste
- 1 can (14 ounces) fire-roasted tomatoes
- 2 cups diced potatoes
- About 2 cups beef broth
- Olive oil for cooking
The seasoning stays focused on garlic, oregano, and salt.
The lamb contributes its own flavor, while the tomatoes and broth create the cooking liquid.
Black pepper can be added to taste before serving.
Red wine can add another layer, but it isn’t required
Some lamb stews use red wine to build a richer sauce.
This version doesn’t require it.
If you want to include wine, add it around the same stage as the beef broth.
Rosemary, bay leaves, parsley, or mint can also complement lamb, but adding several herbs isn’t necessary to follow the recipe.
The fire-roasted tomatoes already contribute a flavor that ordinary diced tomatoes won’t reproduce in the same way.
Don’t stop cooking just because the potatoes are tender
Potatoes and lamb don’t always become tender at the same time.
Small potato pieces may soften within the recipe’s suggested simmering period, while lamb from a tougher cut can need longer.
If the potatoes are tender but the meat still resists a fork, continue cooking at a gentle simmer.
Add more broth if the liquid reduces too far.
For a stew with lamb that breaks apart under a fork, allow enough time for the meat’s connective tissue to soften.
The tomatoes improve the broth’s flavor, but they don’t eliminate the cooking time required by the cut of meat.
Leave the potatoes out if you plan to freeze the stew
Lamb stew can be frozen for up to three months when cooled and packed in suitable freezer containers.
Potatoes are less reliable after freezing because their texture can become grainy during thawing and reheating.
If you’re preparing a batch specifically for the freezer, omit the potatoes.
Add cooked potatoes when reheating the stew, or serve it over mashed potatoes or polenta.
The tomato-based broth, lamb, and carrots can be prepared ahead without depending on the potatoes for the finished dish.
Fire-roasted tomatoes don’t replace proper browning or enough simmering time, but they change the flavor of the liquid surrounding the meat. Combined with tomato paste and beef broth, they give lamb stew a roasted tomato base without requiring another handful of spices.
