This thrifty, nostalgic recipe is the ultimate definition of comfort food on a budget. Using just a few pantry staples—dry macaroni, canned peas, and butter—this slow cooker dish transforms into a creamy, warm, and filling meal. It tastes like it was watched over all afternoon, but requires almost zero effort.

Ingredients
- 2 cups dry elbow macaroni
- 2 cups water
- 2 cans (15 oz each) peas, undrained
- ½ cup (1 stick) unsalted butter, cut into pieces
- 1 tsp salt (or to taste)
- ½ tsp black pepper (optional, to taste)
Instructions
- Prep the Slow Cooker: Lightly grease the inside of a small slow cooker (about 3 to 4 quarts) with a bit of butter to help prevent the pasta from sticking.
- Layer the Base: Pour the dry elbow macaroni into the slow cooker and spread it into an even layer.
- Add the Liquids: Pour the canned peas—along with all of their liquid—over the macaroni. Add the water and gently stir so the pasta is mostly submerged.
- Season and Butter: Scatter the butter pieces evenly over the top of the mixture. Sprinkle with salt and black pepper.
- Cook: Cover the slow cooker and cook on LOW for 1 ½ to 2 hours. Be sure to stir once or twice during cooking. The dish is done when the macaroni is very tender and the peas are soft.
- Stir and Serve: Once done, give everything a vigorous stir. The peas will break up slightly and blend with the melted butter and pasta starch to create a glossy, pale green sauce. Taste, adjust the salt and pepper if needed, and serve warm!
Common Mistakes to Avoid
- Draining the canned peas: This is the most critical mistake you can make with this recipe! The liquid inside the can is packed with starch and sodium, which is essential for cooking the dry pasta and creating that glossy, thick sauce.
- Using a slow cooker that is too large: This recipe is designed for a smaller 3 to 4-quart slow cooker. If you use a large 6 to 8-quart slow cooker, the liquid will spread out too thinly, leaving the macaroni exposed to dry out instead of simmering in the sauce.
- Forgetting to stir: While slow cookers are mostly hands-off, pasta needs a little attention. Stirring once or twice during the cooking process prevents the macaroni from clumping together or sticking to the bottom of the pot.
Can I add meat to make this more filling?
Yes, this is a great base for using up leftovers. For a boost of protein, simply stir in some leftover diced ham, cooked crumbled bacon, or shredded rotisserie chicken during the last 15 minutes of cooking so it has time to warm through.
How can I make the sauce richer?
If you prefer an even creamier, richer texture, you can stir in a splash of whole milk or a spoonful of sour cream right at the end of the cooking time. Tossing in a handful of shredded cheddar or American cheese will also melt beautifully into the hot pasta, giving it a cheesy, casserole-like finish.
Can I use frozen peas instead of canned?
While you technically can, it will change the nature of the recipe. This specific dish relies heavily on the starchy canning liquid to hydrate the pasta and build the sauce. If you swap to frozen peas, you will need to add extra water or broth to compensate for the missing liquid, and the final sauce won’t be quite as thick or nostalgic.
