Step‑by‑Step Instructions for Slow Cooker Meatball Casserole Step 1: Prepare Meatballs and Sauce Start by adding frozen meatballs to your slow cooker. Pour the marinara sauce over the meatballs and use a spatula to gently stir, ensuring they are evenly coated. This combination of flavors will form a delicious base as the slow cooker works its magic. Set your slow cooker to high for 2-3 hours or low for 4-5 hours, allowing the meatballs to heat through and soak up the sauces. Step 2: Soak in Flavor Cover the slow cooker and let the meatballs simmer. During this time, the marinara will bubble, filling your kitchen with a rich aroma. If you chose the low setting, check for doneness after about 4 hours—the meatballs should be hot in the center and tender to the touch. Once cooked through, prepare the next step by cooking your pasta. Step 3: Add Pasta In the last 30 minutes of cooking, carefully add the cooked pasta, such as penne or rotini, into the slow cooker. Gently stir to combine, ensuring the pasta is well-coated with the sauce and meatballs. Keep the lid on to retain heat while the pasta absorbs the flavors. The casserole should be warm and inviting, a delightful blend of textures taking shape. Step 4: Sprinkle with Cheese Once the pasta is incorporated, sprinkle a generous layer of shredded mozzarella cheese and grated Parmesan on top. Cover the slow cooker again and allow it to cook on low for an additional 20-30 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and slightly golden—a visual treat that promises deliciousness. Step 5: Season to Taste After the cheese has melted, remove the lid and season your Slow Cooker Meatball Casserole with Italian seasoning, salt, and pepper to your liking. Stir gently, allowing the herbs to infuse the dish with their fragrant aroma. Feel free to taste as you go to ensure it’s perfectly seasoned for your family’s palates. Step 6: Garnish and Serve Before serving, sprinkle fresh basil or parsley on top for a pop of color and added freshness. Scoop generous portions of your comforting casserole onto plates, savoring the melted cheese and hearty meatballs. This dish is best enjoyed warm, bringing joy and satisfaction to your family dinner table.
