Ingredients
-
500 g elbow macaroni
-
4 cups milk
-
400 g shredded cheddar cheese
-
100 g shredded mozzarella cheese
-
120 g unsalted butter, melted
-
60 g all-purpose flour
-
1 tsp salt
-
½ tsp black pepper
-
½ tsp garlic powder
-
½ tsp onion powder
-
¼ tsp paprika
Instructions
1. Prep Your Crockpot
Lightly grease the insert of your slow cooker with butter or non-stick spray to prevent sticking.
2. Combine Ingredients
In a large mixing bowl (or directly in the crockpot), whisk together the melted butter and flour until smooth. This forms a roux-like base that will help thicken the cheese sauce as it cooks.
Add the milk, salt, black pepper, garlic powder, onion powder, and paprika, and whisk to combine.
3. Add Pasta & Cheese
Stir in the uncooked elbow macaroni, cheddar cheese, and mozzarella cheese. Mix well to ensure the pasta is evenly coated and the cheese is distributed throughout.
4. Slow Cook
Cover and cook on low for 2 to 2½ hours, stirring every 30 to 45 minutes to prevent sticking and ensure even cooking. The pasta should be tender and the sauce rich and creamy.
🧀 Tip: If your mac and cheese seems too thick near the end, stir in a splash of warm milk to loosen it.
5. Serve Warm
Once the pasta is fully cooked and the cheese is melty and smooth, your Crockpot Mac and Cheese is ready to serve. Spoon into bowls and enjoy immediately for the best texture and flavor.
