These slow cooker 4-ingredient cheesy garlic butter pasta packets are the kind of easy comfort food that feels made for busy weekends, potlucks, and backyard hangouts. Wrapping everything into individual foil packets keeps cleanup simple and makes serving extra fun, and the buttery garlic flavor with melted cheese turns basic pantry staples into something people always want seconds of. This is a smart recipe to keep around when you need a low-effort dish that still feels cozy and a little special.
Serve these pasta packets with grilled chicken, burgers, sausage, or a crisp green salad to balance the richness. They also fit right in on a casual party table with roasted vegetables, corn on the cob, or fresh fruit. If you're setting these out for a gathering, a bowl of extra chopped parsley and a little grated cheese on the side makes them feel even more inviting.
Slow Cooker 4-Ingredient Cheesy Garlic Butter Pasta Packets
Servings: 6
Ingredients
12 ounces rotini pasta, cooked until just tender
1/2 cup salted butter, melted
4 teaspoons garlic powder
2 cups shredded mozzarella cheese
2 tablespoons chopped fresh parsley for garnish (optional)
Directions
1. Tear 6 large sheets of heavy-duty foil and set them on the counter. Lightly spray or butter the center of each sheet so the pasta does not stick.
2. In a large bowl, toss the warm cooked rotini with the melted butter, garlic powder, and shredded mozzarella until everything is evenly coated.
3. Divide the pasta mixture evenly among the foil sheets. Fold and seal each packet tightly so the butter and cheese stay inside while cooking.
4. Arrange the packets in a single layer or slightly overlapping stack inside a white slow cooker. Cover and cook on Low for 1 1/2 to 2 hours, until the cheese is fully melted and the packets are hot all the way through.
5. Carefully open one packet to check that the cheese is melted. Transfer the packets to a serving platter or serve right from the slow cooker, then drizzle with any extra melted butter and sprinkle with parsley if using.
Variations & Tips
Add protein: Stir in cooked shredded chicken, chopped ham, or crumbled cooked sausage before sealing the packets if you want to make these more filling for dinner.
Try another cheese: Mozzarella gives you that classic stretchy melt, but a blend with provolone, Monterey Jack, or mild cheddar works well too if that is what you already have in the fridge.
Make-ahead tip: Assemble the packets a few hours ahead, refrigerate them, and place them in the slow cooker when you're ready to start cooking. This is especially helpful when you're juggling guests or getting other dishes ready.
Prevent overcooking: Since the pasta is already cooked, the slow cooker is mainly there to heat everything through and melt the cheese. Check early so the pasta stays soft and buttery instead of drying out.
Easy cleanup: Use heavy-duty foil and make sure each packet is sealed well. If you're taking these to a gathering, you can stack them in the cooker, transport them warm, and let everyone grab their own packet.
