- For the Beef & Vegetables:
- 1 ½ pounds lean ground beef (80/20 or 90/10)
- 1 large yellow onion, chopped
- 2 cloves garlic, minced
- 1 red bell pepper, chopped
- 1 green bell pepper, chopped
- 1 cup frozen corn (optional)
- 1 cup frozen peas (optional)
- For the Sauce:
- 1 (28 ounce) can crushed tomatoes
- 1 (15 ounce) can diced tomatoes, undrained
- 2 tablespoons tomato paste
- 1 cup beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried Italian seasoning
- ½ teaspoon salt, or to taste
- ¼ teaspoon black pepper, or to taste
- For the Pasta & Topping:
- 2 cups uncooked elbow macaroni or small pasta shells
- 2 cups shredded cheddar cheese

- Fresh parsley, chopped, for garnish (optional)
Step-by-Step Instructions
-
Step 1: Brown the Beef
In a large skillet, cook the ground beef over medium-high heat. Break it up with a spoon as it cooks. Drain off any excess grease once it’s fully browned. Transfer the cooked beef to your slow cooker.
Small tip: Leaner ground beef will result in less grease to drain, making this step quicker and healthier.
-
Step 2: Sauté Aromatics
In the same skillet (no need to clean it!), add a tiny bit of olive oil if necessary. Sauté the chopped onion and bell peppers for about 5-7 minutes until they start to soften. Add the minced garlic and cook for another minute until fragrant. Transfer these softened vegetables to the slow cooker with the beef.
Small tip: Don’t skip sautéing the vegetables! It brings out their sweetness and deepens the overall flavor of the casserole.
-
Step 3: Combine Sauce Ingredients
To the slow cooker, add the crushed tomatoes, diced tomatoes (with their liquid), tomato paste, beef broth, Worcestershire sauce, Italian seasoning, salt, and pepper. Stir everything together gently until all ingredients are well combined. Make sure the beef and vegetables are coated in the sauce.
Small tip: If you like a little extra kick, a pinch of red pepper flakes can be added here.
-
Step 4: Cook Low and Slow
Cover your slow cooker and cook on low for 6-8 hours or on high for 3-4 hours. The goal is for the flavors to meld beautifully and the beef to become incredibly tender. The sauce will thicken slightly during this time.
Small tip: Resist the urge to lift the lid too often, as this releases heat and extends the cooking time.
-
Step 5: Add Pasta and Cheese
About 30-45 minutes before serving, stir in the uncooked elbow macaroni (or other small pasta), frozen corn, and frozen peas (if using). Stir well to ensure the pasta is submerged in the liquid. Cover again and continue cooking until the pasta is tender.
Small tip: Ensure there’s enough liquid to cook the pasta; if it looks a bit dry, add a splash more beef broth or water.
-
Step 6: Final Touch and Serve
Once the pasta is cooked through, sprinkle the shredded cheddar and mozzarella cheeses evenly over the top of the casserole. Place the lid back on for about 10-15 minutes, or until the cheese is beautifully melted and bubbly. Garnish with fresh parsley if desired, then scoop and serve immediately!
Small tip: For an extra golden-brown cheese crust, you can carefully transfer the slow cooker insert (if oven-safe) to a preheated broiler for a few minutes, watching it very closely.
Tips & Variations
- Gluten-Free Option: Easily make this casserole gluten-free by using gluten-free elbow macaroni or your preferred small gluten-free pasta. Always double-check that your beef broth and Worcestershire sauce are also certified gluten-free.
- Vegan or Vegetarian Option: Replace the ground beef with cooked lentils, crumbled tempeh, or a plant-based ground “meat” substitute. Use vegetable broth instead of beef broth, and opt for your favorite dairy-free shredded cheese.
- More Vegetables or Protein: Boost the nutrition by adding extra vegetables like diced carrots, zucchini, or spinach during the last hour of cooking. For more protein, you can swap half the ground beef for ground turkey or add a can of drained and rinsed kidney beans or black beans with the sauce ingredients.
- Spicy Version: For those who love a kick, add ½ to 1 teaspoon of chili powder, a pinch of red pepper flakes, or a finely diced jalapeño pepper along with the onion and bell peppers. A dash of hot sauce at the end also works wonders!
- Flavor Boosters: Experiment with different cheese blends like Monterey Jack or a Mexican blend. A teaspoon of smoked paprika can add a lovely depth of flavor. Fresh basil or oregano stirred in at the end can also brighten the dish.

Health Benefits
This Slow Cooker Ground Beef Casserole isn’t just delicious; it also offers some great health benefits thanks to its wholesome ingredients.
Ground beef, especially lean varieties, is an excellent source of high-quality protein, which is essential for muscle repair and growth. It also provides vital nutrients like iron, important for oxygen transport in the blood, and B vitamins (B12, niacin, B6), which play a key role in energy metabolism and nerve function.
The array of vegetables in this casserole, such as bell peppers, onions, and tomatoes, contribute a wealth of vitamins and antioxidants. Bell peppers are packed with Vitamin C, a powerful antioxidant that supports immune health, and Vitamin A. Tomatoes are rich in lycopene, another antioxidant linked to heart health.
Even the humble onion and garlic offer health perks. Onions contain compounds that may help reduce inflammation, while garlic is known for its immune-boosting and cardiovascular benefits. Together, they add not only incredible flavor but also a nutritional punch to your meal.
When paired with whole wheat pasta (if you choose that option), this dish also provides beneficial dietary fiber, aiding digestion and promoting a feeling of fullness. Overall, it’s a well-rounded meal that can contribute to a balanced diet.
