What You’ll Need
- 1 pound ground beef (or ground turkey, chicken, or plant-based crumbles)
- 1 tablespoon olive oil (if using lean meat or for sautéing vegetables)
- 1 medium yellow onion, diced
- 3 bell peppers (any color), diced
- 3–4 garlic cloves, minced
- 1 (28-ounce) can crushed tomatoes
- 1 (15-ounce) can tomato sauce
- 4 cups low-sodium beef broth (or chicken/vegetable broth)
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon smoked paprika (optional)
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon black pepper
- 3/4 cup uncooked long-grain white rice (or brown rice, see Tips)
- Shredded cheese (cheddar, mozzarella, or Monterey Jack), for serving (optional)
- Fresh parsley, for garnish (optional)
Step-by-Step
- Prep all your ingredients. Dice the onion and bell peppers, mince the garlic, and measure out your spices and rice. Open your cans of tomatoes and sauce.
- Set the Instant Pot to Sauté. Press the Sauté button and allow it to heat up. Add olive oil if using lean ground meat or just to help sauté the vegetables.
- Brown the ground beef. Add the ground beef to the pot, breaking it up with a spoon. Cook until browned and no longer pink, about 5–7 minutes. If there’s excess grease, drain it off.
- Add onion and peppers. Stir in the diced onion and bell peppers. Sauté for 3–5 minutes until slightly softened. Add the minced garlic and sauté for 1 minute until fragrant.
- Deglaze the pot. Pour in a splash of broth and use a wooden spoon to scrape up any browned bits on the bottom. This helps prevent the “burn” warning when pressure cooking.
- Add remaining ingredients (except rice). Stir in the crushed tomatoes, tomato sauce, the rest of the broth, oregano, basil, smoked paprika (if using), salt, and pepper. Mix well.
- Add the rice. Stir in the uncooked rice. Make sure it’s submerged in the liquid, but don’t stir too vigorously—just enough to combine.
- Pressure cook. Secure the lid, set the valve to Sealing, and select Manual/Pressure Cook for 8 minutes (for white rice; see Tips for brown rice timing).
- Natural release for 5 minutes. When cooking is complete, let the pressure release naturally for 5 minutes. Then carefully perform a quick release by turning the valve to Venting (use a towel or utensil for safety).
- Open, stir, and check consistency. Stir the soup. If it’s too thick, add more broth to reach your preferred consistency. Taste and adjust seasoning as needed.
- Serve and garnish. Ladle into bowls. Top with shredded cheese and parsley if desired. Enjoy hot!
Common Mistakes
- Forgetting to deglaze the pot: Skipping this step can trigger the Instant Pot’s burn warning during pressure cooking.
- Adding too much rice: More rice than recommended makes the soup overly thick and can absorb too much liquid.
- Not adjusting for brown rice: Brown rice needs more time and liquid; using the same timing as white rice leads to undercooked grains.
- Overcooking vegetables: Sautéing peppers and onions too long before pressure cooking can make them mushy.
- Not tasting before serving: Soup may need more salt or acid (a splash of vinegar or lemon) for balanced flavor.
Tips
- Make it vegetarian: Swap ground beef for plant-based crumbles or cooked lentils, and use vegetable broth.
- Use brown rice: Increase pressure cook time to 15 minutes and add 1/4 cup more broth. Or cook rice separately and stir it in after.
- Prep ahead: Dice vegetables and measure spices in advance for a faster weeknight meal.
- Double the recipe: This soup freezes well. Make a double batch and freeze portions for later (see storage below).
- Customize veggies: Add chopped carrots, celery, or zucchini for extra nutrition and flavor.
- Cheesy topping: Stir in cheese at the end for extra creaminess, or let guests add their own.
- Make it spicy: Add a pinch of red pepper flakes or diced jalapeño for heat.
- Low-carb version: Omit rice or substitute with cauliflower rice (add after pressure cooking and let heat through).
Troubleshooting
- Burn warning: If the Instant Pot displays a burn warning, cancel cooking, release pressure, and open the lid. Stir well, scraping the bottom. Add a splash more broth if needed, then resume cooking.
- Soup is too thick: Stir in extra broth or water after cooking until you reach the desired consistency.
- Soup is too thin: Use the Sauté function after pressure cooking to simmer and reduce the soup, or add more cooked rice.
- Rice is undercooked: Replace the lid and cook on Manual/Pressure Cook for another 2–3 minutes, then quick release.
- Rice is mushy: Next time, try a shorter cook time or add rice after pressure cooking, letting it simmer until tender.
- Lacking flavor: Add more salt, fresh herbs, or a splash of vinegar or lemon juice to brighten the soup.
- Soup tastes acidic: Stir in a pinch of sugar or a splash of cream to balance the acidity from tomatoes.
- Leftovers too thick: Rice continues to absorb liquid as it sits. When reheating, add broth or water to loosen the soup.
Frequently Asked Questions
- Can I use ground turkey or chicken instead of beef?
Yes, both work well. Use olive oil for sautéing, as they’re leaner than beef. - How do I make this soup gluten-free?
All main ingredients are naturally gluten-free. Double-check broth labels to ensure there are no added gluten-containing ingredients. - Can I freeze stuffed pepper soup?
Absolutely! Cool completely, portion into airtight containers, and freeze for up to 3 months. Thaw overnight in the fridge and reheat gently, adding a little broth if needed. - How long does stuffed pepper soup last in the fridge?
Store in a covered container for up to 4 days. Rice will absorb liquid, so add broth when reheating. - Can I use pre-cooked rice?
Yes. Stir in cooked rice after pressure cooking and let it heat through for 5–10 minutes on the Keep Warm or Sauté setting. - How do I prevent the burn warning?
Always deglaze the pot after sautéing, and make sure there’s enough liquid before sealing. Avoid stirring tomato products to the bottom of the pot. - What cheese goes best with stuffed pepper soup?
Cheddar, mozzarella, or Monterey Jack are all excellent choices. Add a sprinkle just before serving for a melty finish.
