1 (10.5-ounce) can condensed cream of chicken soup
3 cups shredded cheddar cheese
1 cup shredded Gruyère cheese
½ cup mayonnaise
½ cup sour cream (regular or light)
1 teaspoon onion powder
½ teaspoon dry mustard powder
½ teaspoon black pepper
Instructions
Cook the Pasta: Boil the macaroni according to package directions but stop 1-2 minutes early so it remains firm. (Aim for about 5 minutes of boiling.) Drain and rinse with cold water.
Mix Ingredients: In a 4-quart slow cooker, combine all ingredients, including the cooked pasta. Stir to distribute everything evenly.
Slow Cook: Cover and cook on high for 2 hours or low for 3 hours, stirring once or twice during cooking.
Serve: Enjoy hot and creamy!
Tips & Variations
Pasta: Keep it firm after boiling; rinsing helps stop the cooking process.
Cheese: For best results, shred cheese from a block instead of using pre-shredded cheese. No Gruyère? Substitute with an extra cup of cheddar.
Cooking Time: Check the pasta early—slow cooker temperatures can vary.
Doubling the Recipe: Use a 6-quart slow cooker if doubling. Cook on high for 2½ hours, stirring at the 1-hour and 2-hour marks.
Make-Ahead Option: Prep the sauce and cooked pasta separately, then combine in the slow cooker before cooking.
Oven Alternative: Preheat to 350°F. Bake covered for 30 minutes, then uncovered for another 30 minutes.
