Crockpot Stuffed Pepper Soup Recipe

Step 1: Brown the Beef and Onion

Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add 1½ pounds lean ground beef and 1 cup diced onion. Cook for 6–8 minutes, breaking the beef into small crumbles with a wooden spoon. The beef should be fully browned with no pink left, and the onion should look soft. Drain off excess grease if needed.

Step 2: Fill the Crockpot

Transfer all of the browned 1½ pounds ground beef and softened 1 cup diced onion to a black oval crockpot. Add 1 cup diced green bell pepper, 1 cup diced red bell pepper, 3 minced garlic cloves, 28 ounces crushed tomatoes, 14.5 ounces diced tomatoes with their juices, 4 cups low-sodium beef broth, 2 tablespoons tomato paste, 1 tablespoon Worcestershire sauce, 1 teaspoon Italian seasoning, 1 teaspoon smoked paprika, 1 teaspoon kosher salt, and ½ teaspoon black pepper. Stir until the tomato paste and seasonings are mixed into the broth.

Step 3: Slow Cook the Soup

Put the lid on the black oval crockpot. Cook on LOW for 6–7 hours or HIGH for 3–4 hours. When done, the 1 cup green bell pepper and 1 cup red bell pepper should be tender, the onion should be very soft, and the tomato and beef broth should taste rich and blended.

Step 4: Cook the Rice

About 25 minutes before serving, place 1 cup uncooked long-grain white rice and 2 cups water in a medium saucepan. Bring to a boil. Cover, reduce the heat to low, and cook for about 15–18 minutes, or according to the rice package. Remove from the heat and fluff with a fork.

Step 5: Finish the Soup

Stir about 3 cups cooked white rice from Step 4 into the hot soup. Add 2 tablespoons chopped fresh parsley and stir gently. Let the soup sit in the crockpot for about 5 minutes so the rice warms through. Taste and adjust the seasoning only if needed.

Step 6: Serve

Ladle the hot soup into round bowls. Serve right away.

Why This Recipe Works (Quick Science)

Browning the ground beef first does more than cook it. The high heat creates deeper, savory flavors that a crockpot cannot make as well on its own.

Slow cooking gives the peppers and onion plenty of time to soften. It also lets the tomato, beef broth, garlic, and seasonings blend together.

The biggest trick is cooking the rice separately. Rice keeps absorbing liquid after it cooks. If raw rice sits in the crockpot for hours, it can become mushy and make the soup much too thick. Adding fluffy cooked rice near the end gives you more control.

Pro Tips

• Cut the peppers evenly. Small, similar-sized pieces cook at the same speed.
• Do not skip browning the beef. It makes the soup taste much richer.
• Keep the rice separate until the end. This is the easiest way to avoid mushy rice.
• Want a thinner soup? Add a little extra beef broth before serving.
• Add cheese to individual bowls. Everyone can decide how much they want.

Tools You’ll Need

• Black oval crockpot, 6-quart size or larger
• Large skillet
• Medium saucepan with lid
• Chef’s knife
• Cutting board
• Wooden spoon
• Measuring cups
• Measuring spoons
• Can opener
• Colander for draining beef if needed
• Fork
• Soup ladle
• Round serving bowls

Substitutions and Variations

• Ground turkey: Use 1½ pounds instead of ground beef.
• Different peppers: Use orange or red bell peppers in place of green.
• Brown rice: Cook it separately according to its package, then add it at the end.
• Spicy: Add ¼–½ teaspoon crushed red pepper flakes.
• More vegetables: Add 1 cup diced zucchini during the last 1–2 hours.
• No cheese: Leave the cheddar off. The soup is still rich and filling.
• Lower sodium: Choose no-salt-added tomatoes and low-sodium broth.

Make Ahead Tips

Dice the onion and bell peppers up to 2 days ahead and keep them covered in the refrigerator.

You can also brown the ground beef and onion a day ahead. Cool them quickly, refrigerate them in a sealed container, and add them to the crockpot the next day.

For the best texture, wait to cook and add the rice until close to serving time.

Common Mistakes

• Adding raw rice at the beginning: It can overcook and absorb too much broth.
• Skipping the beef-browning step: The beef will not have the same deep flavor.
• Cutting huge pepper pieces: Large pieces may still be firm when the rest of the soup is ready.
• Using very fatty beef without draining it: This can leave a layer of grease on the soup.
• Adding all the cheese to the crockpot: It can change the texture. Cheese works better as a topping.
• Leaving cooked rice in the soup for hours: It will continue soaking up liquid.

What to Serve With

This soup is filling on its own, but a simple side makes it feel like a full dinner.

• Warm garlic bread
• Crusty bread or dinner rolls
• Grilled cheese
• Simple green salad
• Roasted broccoli
• Cornbread
• Crackers for dipping

Macros Information

Estimated per serving, based on 8 servings and without optional cheddar cheese:

• Calories: About 390
• Protein: About 25 g
• Carbohydrates: About 43 g
• Fat: About 13 g
• Fiber: About 5 g
• Sugar: About 9 g

These numbers are estimates. The exact macros will change based on the ground beef, broth, tomatoes, rice, and toppings you use.

Leftovers and Storage

Store leftover soup in an airtight container in the refrigerator for up to 4 days.

The rice will continue soaking up broth while it sits. For planned leftovers, an even better option is to keep the cooked rice and soup in separate containers. Add rice to each bowl when reheating.

Freeze the soup without the rice for the best texture. Let it cool, place it in freezer-safe containers, and freeze for up to 3 months. Thaw it overnight in the refrigerator and reheat until steaming hot. Make fresh rice to add before serving.

If you have already mixed in the rice, you can still freeze the soup, but the rice will be much softer after reheating.

FAQ

Q: Can I put uncooked rice straight into the crockpot?
A: I do not recommend it for this recipe. Cooking the rice separately gives you a much better texture and keeps it from drinking up all the broth.

Q: Do I have to brown the ground beef first?
A: Yes, for the best result. Browning improves the flavor and lets you drain away extra grease before it goes into the soup.

Q: Can I cook this on HIGH?
A: Yes. Cook it for about 3–4 hours on HIGH instead of 6–7 hours on LOW. The peppers should be tender before you finish the soup.

Q: Why did my soup get so thick overnight?
A: The cooked rice keeps absorbing broth as it sits. Stir in a splash of beef broth when reheating it.

Q: Can I freeze Crockpot Stuffed Pepper Soup?
A: Yes. For the best result, freeze the soup before adding the rice. Cook fresh rice when you are ready to serve it.

Q: Can I use ground turkey?
A: Yes. Replace the 1½ pounds of ground beef with the same amount of ground turkey and brown it before adding it to the crockpot.

Q: Is the cheese required?
A: No. The cheddar is only a topping, so you can leave it off completely.
