Ingredients

- 1 cup (2 sticks) unsalted butter, cut into chunks
- 2 cups frozen sweet green peas
- 1 teaspoon salt (optional, to taste)
Ingredient Notes
Macaroni:
Elbow macaroni works best because it cooks evenly in the slow cooker and holds the buttery sauce well.
Butter:
This is the key ingredient that makes the dish rich and creamy. Use unsalted butter so you can control the salt level.
Sweet Peas:
Frozen peas are convenient and add natural sweetness, color, and nutrition.
Water:
Hot water helps jumpstart the cooking process and ensures even cooking.
Step-by-Step Instructions
Step 1: Prepare the Slow Cooker
Lightly grease the inside of your slow cooker crock with butter or cooking spray. This helps prevent sticking and makes cleanup easier.
Step 2: Add the Macaroni
Pour the dry elbow macaroni directly into the slow cooker. Spread it evenly across the bottom.
Step 3: Add Hot Water
Carefully pour in 3 cups of hot water. Make sure the pasta is mostly submerged to ensure even cooking.
Step 4: Add Butter
Place the chunks of butter on top of the macaroni. As it melts, it will coat the pasta and create a rich, creamy texture.
Step 5: Start Cooking
Cover the slow cooker with the lid and cook on:
- HIGH for 1.5 to 2 hours, or
- LOW for 2.5 to 3 hours
Step 6: Stir Occasionally
Stir the pasta every 30–40 minutes if possible. This prevents sticking and helps cook the macaroni evenly.
Step 7: Add Sweet Peas
About 20–30 minutes before the cooking time ends, add the frozen sweet peas. Stir well to combine.
Step 8: Season and Finish
Add salt to taste and give everything a final stir. Cook until the macaroni is tender and the peas are heated through.
Tips for Best Results
- Don’t overcook, or the pasta may become mushy
- Stir occasionally for even texture
- Add a splash of milk if it looks too thick
- Taste before adding salt (butter already adds flavor)
Optional Add-Ins
Want to enhance the flavor? Try adding:
- Shredded cheddar cheese for a cheesy version
- Garlic powder or onion powder for extra depth
- Cooked chicken or tuna for added protein
- Black pepper or chili flakes for a little heat
Storage & Reheating
Refrigerator:
Store leftovers in an airtight container for up to 3 days.
Reheating:
Reheat in the microwave or on the stovetop. Add a splash of milk or water to restore creaminess.
