How to Make Crockpot Cheesy Beef and Pepper Casserole
-
Prepare the slow cooker: Lightly grease a 6-quart slow cooker with nonstick cooking spray to prevent sticking and make serving easier later on.
-
Cook the beef: Heat olive oil in a large skillet over medium-high heat. Brown the ground beef for 7–9 minutes, breaking it into crumbles, until it’s fully cooked to 160°F (71°C). Drain any excess grease to keep the casserole from being greasy.
-
Sauté the onions and garlic: Add the diced onion to the cooked beef and sauté for 3 minutes until softened. Then, stir in the minced garlic and cook for another 30 seconds until fragrant and delightful.
-
Dice the vegetables: Wash and dice the potatoes into evenly sized ½-inch cubes. Also, dice the red, green, and yellow bell peppers into bite-sized pieces for that colorful, delicious mix.
-
Layer the ingredients: Place the diced potatoes in the bottom of the slow cooker. Add the bell peppers on top before spreading the cooked beef and onion mixture evenly over the vegetables.
-
Mix the sauce: In a mixing bowl, combine the tomato sauce, low-sodium beef broth, tomato paste, and all the seasoning (Italian, smoked paprika, garlic powder, onion powder, salt, and black pepper). Stir until smooth and fragrant.
-
Combine and cook: Pour the seasoned tomato sauce over the beef and vegetables. Gently stir to distribute the sauce while keeping most of the potatoes at the bottom. Cover and cook on LOW for 5–6 hours or HIGH for 3–4 hours until the potatoes are fork-tender and peppers are soft.
-
Add the cheese: Sprinkle 1 cup of cheddar cheese over the casserole and gently stir until incorporated. Spread the remaining 1 cup of cheddar and ½ cup of mozzarella evenly over the top.
-
Melt the cheese: Cover and cook on LOW for another 10–15 minutes until the cheese is completely melted and bubbly.
-
Rest and serve: Turn off the crockpot and let the casserole rest uncovered for 5–10 minutes. Sprinkle freshly chopped parsley over the melted cheese and serve warm directly from the slow cooker for that inviting home-cooked experience.

Crockpot Cheesy Beef and Pepper Casserole Recipe FAQs
What kind of beef should I use for this casserole?
Absolutely! Lean ground beef is the star of this casserole, contributing a hearty protein base without an overload of fat. I recommend a lean ground beef to keep the dish balanced and flavorful without being greasy.
How do I know if my bell peppers are ripe?
When selecting bell peppers, look for ones that are firm and glossy with vibrant colors. Avoid any with wrinkled skin or dark spots, as these indicate overripeness. If your bell peppers have a slight sheen and feel heavy for their size, they’re perfect for your casserole!

Yes, you can! To freeze, wait until the casserole has completely cooled, then transfer it to a tightly sealed, freezer-safe container. It can be stored for up to 3 months. For best results, consider portioning it into smaller containers, making reheating quick and easy.
What is the best way to reheat the casserole after freezing?
To reheat, thaw in the fridge overnight for best results. Then, warm the casserole in an oven preheated to 350°F (175°C) for about 30 minutes, or until heated through. You can also microwave individual portions for a speedy meal—just be sure to stir it halfway through for even warming!
Are there any dietary considerations for this recipe?
Very! This casserole contains beef, cheese, and may include gluten, so it’s not suitable for those with dairy or gluten allergies. For a gluten-free option, ensure your broth and tomato products are certified gluten-free. If it’s about sharing with pets, be mindful that ingredients like onion and garlic can be harmful to dogs, so it’s best to keep this casserole just for humans!
How long does this casserole last in the refrigerator?
The casserole will stay fresh in an airtight container for up to 3 days in the fridge. Make sure it cools completely before sealing to avoid condensation, which can affect the texture. Enjoy the cozy flavors for a few days or follow the freezing tips for longer storage!
