• Diced Tomatoes: 1 (28 ounce) can Petite Diced Tomatoes, undrained
• Tomato Sauce: 1 (15 ounce) can Tomato Sauce

Step-by-Step Instructions for Perfect Slow Cooker Stuffed Pepper Soup

Follow these simple steps to create a flavorful and hearty soup your whole family will enjoy.

H3: Browning the Meat (Optional but Recommended)

1. Heat Oil: Place a large skillet over medium-high heat. Add 1 tablespoon of olive oil (or your preferred cooking oil).
2. Cook Onion: Once the oil is shimmering, add the chopped yellow onion. Sauté for 3-5 minutes, stirring occasionally, until the onion begins to soften and become translucent.
3. Add Ground Meat: Add the ground beef (or your chosen meat) to the skillet with the onions. Break it apart with a spoon or spatula.
4. Brown the Meat: Cook the meat, stirring frequently, until it is browned and no longer pink. This usually takes about 7-10 minutes.
5. Add Garlic: Stir in the minced garlic and cook for about 1 minute more, until fragrant. Be careful not to burn the garlic.
6. Drain Excess Fat: Carefully tilt the skillet and spoon out any excess grease, or drain the mixture through a colander. This step is crucial for preventing a greasy soup, especially if using higher-fat meat.
7. Transfer to Slow Cooker: Transfer the browned meat, onion, and garlic mixture to the insert of your slow cooker (minimum 6-quart size recommended).
   • Note: If you prefer to skip browning for maximum ease, you can add the raw ground meat directly to the slow cooker along with the other ingredients (except rice). Break it up as much as possible. The texture will be slightly different, and you won’t get the flavor depth from browning, but it will still be delicious. Ensure you drain any excess fat after cooking, before adding the rice.

H3: Combining Ingredients in the Slow Cooker

1. Add Vegetables and Liquids: To the slow cooker containing the meat mixture (or raw meat), add the chopped bell peppers, undrained petite diced tomatoes, tomato sauce, 4 cups of beef broth (reserving the rest for potential thinning later), Worcestershire sauce, Italian seasoning, smoked paprika, salt, pepper, and the optional bay leaf.
2. Stir Well: Stir everything together thoroughly to ensure the ingredients are well combined. Make sure the meat is broken up if you added it raw.

H3: Cooking the Soup

1. Set Cooking Time: Secure the lid on the slow cooker.
2. Cook on Low or High: Cook on the LOW heat setting for 6-8 hours OR on the HIGH heat setting for 3-4 hours. Low and slow generally yields slightly more tender vegetables and deeper flavor, but High works well if you’re shorter on time. Choose the setting that best fits your schedule.

H3: Adding the Rice

1. Timing: About 30-60 minutes before the total cooking time is complete (closer to 60 minutes if cooking on LOW, closer to 30-40 minutes if cooking on HIGH), add the uncooked long-grain white rice.
2. Stir In Rice: Remove the slow cooker lid (and the bay leaf, if using), stir in the uncooked rice, ensuring it’s fully submerged in the liquid.
3. Adjust Liquid (If Needed): If the soup seems excessively thick at this point, stir in some or all of the remaining 2 cups of beef broth. The rice will absorb a significant amount of liquid as it cooks.
4. Continue Cooking: Replace the lid and continue cooking on the same heat setting until the rice is tender. This typically takes 30-60 minutes, depending on your slow cooker and the heat setting. Test a grain of rice to check for doneness – it should be soft but not mushy.

H3: Finishing Touches

1. Taste and Adjust Seasoning: Once the rice is cooked, give the soup a final stir. Taste it and adjust the seasonings as needed. You might want more salt, pepper, or even a pinch more Italian seasoning.
2. Rest (Optional): Let the soup rest for 5-10 minutes off the heat before serving. This allows the flavors to meld slightly more.
3. Serve: Ladle the hot soup into bowls.

How to Serve Your Delicious Stuffed Pepper Soup

  • Crusty Bread: A slice of French baguette, sourdough, or Italian bread is perfect.
  • Cornbread: The slight sweetness of cornbread pairs wonderfully with the savory soup.
  • Garlic Bread or Cheese Bread: Elevates the comfort food experience.
  • Crackers: Saltines, oyster crackers, or butter crackers add a nice crunch.
• Simple Side Salad: A light green salad with a simple vinaigrette can provide a fresh contrast to the rich soup.
• Keep it Simple: Honestly, this soup is substantial enough to stand entirely on its own as a complete meal in a bowl.

Pro Tips for Elevating Your Soup Game

Take your Slow Cooker Stuffed Pepper Soup from great to absolutely phenomenal with these extra tips:

1. Roast Your Peppers: For an even deeper, slightly sweeter pepper flavor, consider quickly roasting your chopped peppers under the broiler for 5-10 minutes until slightly charred before adding them to the slow cooker. This adds another layer of complexity.
2. Meat Variations for Flavor: Don’t be afraid to mix your meats! Using half ground beef and half Italian sausage (mild or hot) adds incredible flavor. Ensure sausage is removed from casings before browning. Ground pork or a combination of beef and pork also works well.
3. Boost the Umami: Enhance the savory depth by adding a teaspoon of tomato paste along with the garlic when browning the meat, or stir in a splash of soy sauce (in addition to or instead of some Worcestershire) towards the end of cooking. A dried mushroom powder can also work wonders.
4. Sneak in More Veggies: Finely dice other vegetables like carrots or celery and sauté them with the onion. You can also stir in a few handfuls of fresh baby spinach or chopped kale during the last 15-20 minutes of cooking (after the rice is tender) until wilted for an extra nutritional boost without significantly altering the core flavor.
5. Control the Spice: Easily adjust the heat level. For mild soup, stick to the recipe. For medium heat, add a pinch (1/4 tsp) of crushed red pepper flakes with the other seasonings. For a spicier kick, add more red pepper flakes, a finely diced jalapeño (sautéed with the onions), or a dash of your favorite hot sauce before serving.

Frequently Asked Questions (FAQ)

Here are answers to some common questions about making Slow Cooker Stuffed Pepper Soup:

1. Q: Can I use pre-cooked rice or leftover rice?
   • A: Yes, you can! If using already cooked rice, stir it in during the last 15-20 minutes of cooking time, just long enough for it to heat through thoroughly. You won’t need as much extra broth as you would for uncooked rice. Using cooked rice prevents it from becoming overly mushy. About 2-3 cups of cooked rice is usually equivalent to 1 cup uncooked.
2. Q: Can I make this soup vegetarian or vegan?
   • A: Absolutely! For a vegetarian version, substitute the ground meat with a plant-based ground alternative, lentils (use about 1.5 cups of brown or green lentils, rinsed), or extra beans like black beans or kidney beans (add canned, rinsed beans during the last hour). Use vegetable broth instead of beef broth. For a vegan version, ensure your Worcestershire sauce is vegan (some contain anchovies) or omit it, use vegetable broth, and serve without dairy toppings like cheese or sour cream (use vegan alternatives if desired).
3. Q: How do I store and reheat leftover soup?
   • A: Let the soup cool completely before storing. Transfer leftovers to airtight containers and refrigerate for up to 3-4 days. Reheat gently on the stovetop over medium-low heat or in the microwave until heated through. Note that the rice will continue to absorb liquid upon sitting, so you may need to add a splash of broth or water when reheating to reach your desired consistency.
4. Q: Can I freeze this Stuffed Pepper Soup?
   • A: Yes, this soup freezes reasonably well. Let it cool completely, then transfer it to freezer-safe containers or heavy-duty freezer bags, leaving some headspace for expansion. It’s best stored for 2-3 months. However, rice can sometimes become slightly mushy or change texture upon thawing and reheating. For the best texture, you might consider freezing the soup before adding the rice, then add freshly cooked rice when you reheat the thawed soup. If freezing with rice, thaw overnight in the refrigerator and reheat gently, adding broth if needed.
5. Q: Can I use different types of rice or grains?
   • A: Yes, but cooking times will vary. Brown rice generally takes longer to cook than white rice; you might need to add it earlier (perhaps 1.5-2 hours before the end on Low, or 1 hour on High). Quinoa is a great substitute; add it about 30-45 minutes before the end of cooking time, similar to white rice. Farro or barley can also be used but require longer cooking times – consider adding them closer to the beginning or cooking them separately and adding them at the end. For a low-carb/keto option, omit the rice altogether and stir in cauliflower rice during the last 15-20 minutes of cooking.
