Common Mistakes to Avoid

Not browning the meat properly — Let the ground beef develop browned edges before adding the liquid for deeper flavor.
Adding cauliflower rice too early — Overcooking can make it mushy, so add it toward the end of simmering.
Using too much broth — Excess liquid can make the soup thin and dilute the tomato and beef flavors.
Skipping the seasoning adjustment — Taste near the end and adjust salt, pepper, and Italian seasoning before serving.

Required Equipment

Large Dutch oven or soup pot — Provides enough space for browning and simmering everything evenly.
Wooden spoon — Easily breaks up the ground meat while it browns.
Chef’s knife — Makes quick, even cuts through the peppers and onion.
Ladle — Makes serving the hot soup simple and mess-free.
Airtight containers — Keep individual portions fresh for meal prep.

Storage Instructions

Allow the soup to cool slightly before transferring it to airtight glass or BPA-free containers. Refrigerate within about 2 hours of cooking and enjoy within 3–4 days.

For freezing, divide the cooled soup into individual freezer-safe containers, leaving a little room at the top for expansion. Freeze for up to 2–3 months for best quality.

Thaw frozen portions overnight in the refrigerator when possible. Reheat gently on the stovetop over medium-low heat or in the microwave until steaming hot throughout. Stir before serving.

📝 Ingredients

Makes 6 servings

1½ lb (680 g) lean ground beef, preferably 90–93% lean
3 medium bell peppers, diced — use any combination of red, green, yellow, or orange
1 medium yellow onion, diced
3 cloves garlic, minced
1 can (14.5 oz / 411 g) diced tomatoes, preferably no-salt-added
1 can (8 oz / 227 g) tomato sauce
4 cups (960 ml) low-sodium beef broth
2 cups (200 g) cauliflower rice, fresh or frozen
2 teaspoons Italian seasoning
1 teaspoon smoked paprika
½ teaspoon salt, plus more to taste
½ teaspoon black pepper
1 tablespoon olive oil, only if needed for browning
2 tablespoons fresh parsley, chopped, for serving

Ingredient note: If using frozen cauliflower rice, there is no need to thaw it first; add it directly during the final cooking stage.

Directions

Prepare the vegetables.
Dice the bell peppers and onion into similar-sized pieces so they cook evenly. Mince the garlic and set everything aside.
Brown the beef.
Heat a large Dutch oven over medium-high heat. Add the ground beef and cook for 6–8 minutes, breaking it apart with a wooden spoon. Continue until no pink remains and the meat develops some browned edges. Drain excess fat if necessary.
Cook the aromatics.
Reduce the heat to medium. Add the diced onion and bell peppers and cook for 4–5 minutes, stirring occasionally, until the onion begins to soften and the peppers are slightly tender.
Add the garlic and spices.
Stir in the garlic, Italian seasoning, smoked paprika, salt, and black pepper. Cook for 30–60 seconds, just until fragrant.
Build the broth.
Add the diced tomatoes, tomato sauce, and beef broth. Stir well and scrape the bottom of the pot to release the flavorful browned bits.
Simmer the soup.
Increase the heat to medium-high until the liquid reaches a gentle boil. Then reduce to medium-low, cover partially, and simmer for 20 minutes. The peppers should be tender but not falling apart.
Add the cauliflower rice.
Stir in the cauliflower rice and cook for another 5–7 minutes. It should be tender while retaining a little texture rather than becoming mushy.
Taste and adjust.
Turn the heat to low and taste the broth. Add additional salt, pepper, or Italian seasoning if needed. For a thicker soup, simmer uncovered for another 3–5 minutes.
Serve.
Ladle into bowls and garnish with fresh parsley. The finished soup should have a rich tomato broth, tender vegetables, and evenly distributed beef and cauliflower rice.

High-protein cooking tip: Choose lean ground beef or ground turkey and keep the cauliflower-to-meat ratio moderate. This preserves the hearty texture while keeping protein high relative to calories.
