All-Day Stuffed Pepper Soup for the Slow Cooker
Everything you love about stuffed peppers—sweet peppers, savory beef, and tomatoey richness—turned into a low-effort, cozy soup that simmers itself to perfection.
This is the kind of recipe that answers the “what’s for dinner?” question before you even get home: brown beef, toss everything into the slow cooker, and six hours later you have a bowl that tastes like it cooked for days. It’s tomato-forward and comforting, with chunks of bell pepper and tender rice giving the mouthfeel of a classic stuffed pepper without any of the fuss of hollowing and stuffing vegetables.
Browning the ground beef with onion and garlic before it hits the crock is the small step that makes a big difference—those browned bits build the savory backbone of the soup. A splash of Worcestershire, a hit of paprika and Italian seasoning, plus a bay leaf, layer in warmth and umami while diced tomatoes and tomato sauce provide a bright, silky base. The peppers soften and lend a sweet, slightly smoky note as they slow-simmer with the beef and broth.
Uncooked long-grain rice goes straight into the cooker and soaks up all the braised flavors, but keep an eye on texture: if you prefer a looser broth, add a little extra beef broth toward the end, and if it’s too thin, remove the lid and let it reduce briefly. Drain any excess fat after browning but leave a tablespoon if you like extra richness—small choices up front make this hands-off dish taste thoughtful.
Serve with grated cheese, a drizzle of olive oil, or a sprinkle of fresh parsley for contrast. Leftovers reheat beautifully for lunches; if you plan to freeze portions, cook the rice separately and add it back in when reheating to keep the texture bright. Simple, dependable, and perfect for cool evenings when you want dinner to feel like a warm, familiar hug.
Ingredients
How to Make Slow Cooker Stuffed Pepper Soup
- Trim and dice the onion and bell peppers into roughly 1/2-inch pieces; mince the garlic and set aside.
- Heat the olive oil in a skillet over medium-high heat, add the ground beef and cook until browned, breaking it up with a spoon; add the diced onion and garlic for the last 2 minutes of browning.
- Drain excess fat from the pan (leave a tablespoon for flavor if desired) and stir in the Worcestershire sauce, paprika, Italian seasoning, salt and pepper to coat the meat; remove from heat.
- Transfer the browned beef mixture to the slow cooker and add the diced tomatoes (with their juices), tomato sauce, beef broth, diced bell peppers, uncooked rice and the bay leaf; give everything a good stir to combine.
- Cover and cook on Low for 5.5–6.5 hours (or High for 3–3.5 hours) until the rice is tender and the peppers are soft; check at the shorter time to ensure rice texture you prefer.
- Taste for seasoning about 30 minutes before serving and adjust salt and pepper if needed, remove and discard the bay leaf.
- Stir in half the chopped parsley and let the soup rest for 5 minutes off heat so flavors meld and the rice finishes absorbing liquid.
- Ladle into bowls and top with shredded cheddar and remaining parsley; serve hot with crusty bread if desired.
