Introduction

It’s the kind of dish that makes weeknights effortless and weekends deliciously lazy. Throw it together before work, and come home to the taste of pizzeria perfection — right from your crockpot.

Perfect for family dinners, potlucks, or when you just crave that pizza comfort without turning on the oven, this recipe is pure cheesy joy in a bowl.

Ingredient Overview

  • 1 lb ground beef (or Italian sausage) – This is the hearty base. Beef gives classic comfort, while Italian sausage adds extra spice and flavor.

  • 1 small onion, chopped – Adds sweetness and depth as it cooks down in the sauce.

  • 1 jar (24 oz) pizza or marinara sauce – Choose your favorite! Pizza sauce gives bolder flavor, while marinara is smooth and balanced.

  • 8 oz rotini or penne pasta (uncooked) – The spirals or tubes hold all that cheesy, saucy goodness.

  • 1 ½ cups shredded mozzarella cheese – The star of the show! Go for low-moisture mozzarella for perfect stretch and melt.

  • ½ cup grated Parmesan cheese – Adds saltiness and a nutty finish.

  • 1 cup sliced pepperoni – That signature pizza flavor in every bite. You can also use mini pepperoni for even distribution.

  • 1 tsp Italian seasoning – A blend of oregano, basil, and thyme that ties everything together.

  • Salt & pepper to taste – Season gently since the sauce and cheese already bring saltiness.

Step-by-Step Cooking Instructions

Step 1: Brown the Meat
In a skillet over medium heat, cook the ground beef or sausage with the chopped onion until browned and no pink remains. Drain excess grease to keep the casserole from becoming oily.

Step 2: Mix the Sauce
Add the pizza or marinara sauce, Italian seasoning, and a pinch of salt and pepper to the meat. Stir well and let it simmer for 2–3 minutes to deepen the flavor.

Step 3: Layer in the Crockpot
Spray your slow cooker with nonstick spray. Add a small layer of the sauce mixture at the bottom, then layer:

  • half of the uncooked pasta,

  • half of the remaining sauce,

  • half of the mozzarella, Parmesan, and pepperoni.

Repeat the layers until everything is used up, ending with cheese and pepperoni on top.

Step 4: Cook Low & Slow
Cover and cook on LOW for 3–4 hours or until the pasta is tender and the cheese is melted. Avoid overcooking — you want that perfect gooey texture.

Step 5: Serve & Enjoy
Lift the lid, let it rest for 10 minutes, then serve warm with a sprinkle of extra Parmesan and a side of garlic bread.
