Ground beef: I like to use 80/20 for good flavor and a juicy texture after browning.
Onion: Diced finely for flavor that blends well without big chunks.
Bell peppers: A mix of colors adds brightness and a lovely sweetness.
Beef broth: Use low-sodium if you’re watching salt; it deepens the soup’s savory base.
Petite diced tomatoes: They give a nice texture without making the soup too chunky.
Tomato sauce: Helps thicken and enrich the broth with that classic tomato base.
Granulated garlic: Divided to season both the beef and the broth evenly.

Spicy kick: Add chopped jalapeños or a dash of cayenne pepper if you like some heat. My husband loves this spicy twist!
Different grains: Try quinoa or brown rice for a nuttier texture and extra nutrition.
Extra veggies: Toss in diced zucchini or mushrooms during cooking for an even heartier soup.

How to Make Slow Cooker Stuffed Pepper Soup Recipe

Step 1: Brown the Beef with Flavor

Start by heating a skillet over medium-high heat and browning your ground beef with half the granulated garlic and salt, plus pepper to taste. Browning is key here because it not only improves flavor but helps remove excess fat. Once the meat is nearly browned, stir in the diced onion and cook until it softens — this builds a delicious base for your soup.

Step 2: Combine Everything in the Slow Cooker

Transfer the browned beef mixture into your slow cooker crock, then add the diced bell peppers, beef broth, petite diced tomatoes, tomato sauce, remaining granulated garlic, parsley, and salt. Give it a gentle stir to combine everything evenly. The beauty here is that all the flavors meld together slowly, creating a rich, comforting soup that tastes like a hug in a bowl.

Step 3: Let It Cook Low and Slow

Cover and cook on low for 6 to 8 hours, or on high for 3 to 4 hours. You’ll notice the aroma fills your kitchen, making it nearly impossible to wait! This gentle cooking breaks down the peppers just enough to soften them while keeping a little bite – perfection.

Step 4: Stir in the Rice at the End

In the last 5 to 10 minutes of cooking, stir in the cooked white rice. I’ve found this timing keeps the rice from getting mushy but allows it to soak up some of the delicious broth. Once the rice is warmed through, you’re ready to serve!

Pro Tips for Making Slow Cooker Stuffed Pepper Soup Recipe

Brown the Beef Thoroughly: I always make sure to brown the ground beef well and drain excess fat to avoid a greasy soup.
Divide Your Garlic: Adding garlic in two stages (to beef and to soup) layers the flavor beautifully throughout the dish.
Add Rice Last: Stirring rice in at the end keeps it from getting mushy, which was a game changer for me.
Avoid Overcooking Peppers: Cooking low and slow preserves just enough bite for the peppers so they don’t turn to mush.

Garnishes

I love topping this soup with a sprinkle of shredded cheddar or Monterey Jack cheese – it melts into the hot broth so nicely. A dollop of sour cream or a few fresh parsley leaves bring a cool, fresh contrast that really brightens up each bite. Sometimes I add a pinch of crushed red pepper flakes for a little heat boost, especially when serving to my spice-loving friends.

Side Dishes

This Slow Cooker Stuffed Pepper Soup is hearty enough to be a full meal, but I often pair it with crusty garlic bread or a simple green salad for some freshness. My family especially enjoys a buttery dinner roll on the side – perfect for dipping into every last bit of that savory broth.

Creative Ways to Present

For special occasions or family dinners, I like to serve this soup in mini bread bowls – it makes the meal feel extra cozy and fun. Another idea I tried was layering the soup in clear mugs and topping with cheese and herbs for a pretty presentation that’s perfect for casual get-togethers.

Make Ahead and Storage

Storing Leftovers

I store leftovers in airtight containers in the fridge for up to 3 days. I like to cool the soup slightly before refrigerating to keep the texture of the peppers and beef nice. When you reheat, do it gently to preserve the flavors and avoid overcooking the rice.

Freezing

This soup freezes really well, which makes it perfect for batch cooking. I freeze it without the rice though – I keep them separate because rice can get a bit mushy when frozen and reheated. When you’re ready to eat, thaw and just stir cooked rice into warmed soup.

Reheating

To reheat, warm the soup gently on the stovetop over medium heat, stirring occasionally until heated through. If you’ve kept rice separate, add it in once the soup is hot. This keeps the texture just right and the flavors vibrant, like freshly made.

FAQs

Can I use ground turkey or chicken instead of beef?

Absolutely! Ground turkey or chicken work well in this Slow Cooker Stuffed Pepper Soup Recipe. Just keep an eye on cooking times, as leaner meats may dry out if cooked too long—browning them first with some added oil helps maintain moisture and flavor.
Can I prepare this without a slow cooker?

Yes! You can make this soup on the stovetop by simmering all ingredients (except rice) in a large pot over medium heat for about 30 minutes until peppers are tender, then stir in cooked rice and heat through. Keep an eye on the liquid and add broth if it gets too thick.
Can I add fresh herbs instead of dried parsley?

Fresh parsley is a wonderful swap! Add it near the end of cooking to preserve its bright flavor and color. About 1 tablespoon chopped fresh parsley works well in place of the dried.
How can I make this soup thicker?

If you prefer a thicker soup, you can reduce the beef broth slightly or add an extra half-cup of tomato sauce. Another trick I use is stirring in a small slurry of cornstarch and cold water during the last half hour of cooking.
Is it okay to add rice uncooked into the slow cooker?

I’ve found adding cooked rice at the end gives the best texture. Using uncooked rice in the slow cooker can sometimes cause it to overcook and become mushy, but if you want to try it, add it early with extra liquid and watch the cooking time carefully.

This Slow Cooker Stuffed Pepper Soup Recipe has become one of those meals I turn to when I want something hearty, easy, and bursting with the flavors I grew up loving in stuffed peppers.
