Ingredients

Servings: 4

• 2 cups dry elbow macaroni
• 2 cups water
• 2 cans (15 ounces each) canned peas, undrained
• 1/2 cup unsalted butter, cut into pieces
• 1 teaspoon salt, or to taste
• 1/2 teaspoon black pepper, optional

How to Make Slow Cooker Pea Macaroni

1. Prepare the slow cooker

Lightly grease a 3- to 4-quart slow cooker with a little butter. This helps reduce sticking as the macaroni cooks.

2. Add the macaroni

Pour the dry elbow macaroni into the slow cooker and spread it into an even layer.

3. Add the peas and water

Pour both cans of peas, including their liquid, over the macaroni. Add the water and gently stir so most of the pasta is covered by the liquid.

4. Add the butter and seasoning

Scatter the butter pieces over the top. Add the salt and optional black pepper.

5. Slow cook

Cover and cook on LOW for about 1 1/2 to 2 hours, stirring once or twice during cooking. Cook until the macaroni is very tender and the peas have softened.

Because slow cookers vary, start checking the pasta toward the earlier end of the cooking time to prevent it from becoming overly soft.

6. Stir until creamy

Once the macaroni is tender, stir everything thoroughly. Some of the peas will naturally break apart and combine with the butter and pasta starch, creating a simple, creamy sauce that coats the noodles.

Taste and add more salt or pepper if needed.

Serve warm directly from the slow cooker.

What Makes This a Great Budget Meal?

This 3-ingredient macaroni recipe is built around inexpensive ingredients that many people already have in the pantry. Dry pasta provides an affordable base, canned peas add vegetables and texture, and butter brings richness without requiring a complicated sauce.

It’s especially useful for those evenings when you want a homemade meal but don’t want to make another trip to the grocery store.

For an even more complete dinner, serve it with sliced tomatoes, a simple green salad, roasted vegetables, or leftover cooked chicken.

Easy Variations

The basic recipe is intentionally simple, but there are plenty of ways to customize this creamy pea macaroni.

Make It Cheesy

Stir in a handful of shredded cheddar cheese or another favorite melting cheese after cooking. Let it melt into the hot macaroni before serving.

Add Protein

For a heartier meal, stir in diced cooked ham, shredded rotisserie chicken, or another leftover cooked meat during the final few minutes of cooking.

Add Extra Creaminess

For a richer texture, stir in a small splash of milk or a spoonful of sour cream after the macaroni has finished cooking.

Add More Seasoning

Garlic powder, onion powder, dried herbs, or fresh parsley can add extra flavor without requiring many additional ingredients.

Use Mixed Vegetables

If you don’t have enough peas, substitute one can with canned mixed vegetables for a slightly different version of this easy pantry meal.

What to Serve With Pea Macaroni

This simple macaroni dish works well as either a budget-friendly main dish or an easy side dish.

Try serving it with:

• Fresh sliced tomatoes
• Green salad
• Steamed vegetables
• Roast chicken
• Meatloaf
• Buttered bread
• Warm dinner rolls

For a nostalgic comfort-food dinner, pair the creamy macaroni with meatloaf and a simple vegetable side.

Storage and Food Safety

Use canned peas that are within their expiration date and avoid cans that are bulging, leaking, heavily rusted, or badly dented. If the contents look or smell unusual after opening, discard them.

Refrigerate leftovers promptly in shallow containers. Avoid leaving cooked macaroni at room temperature for more than about 2 hours.

When reheating leftovers, heat the portion thoroughly until steaming hot. Add a small splash of water or milk if the macaroni has thickened in the refrigerator.

Frequently Asked Questions

Can I make pea macaroni without a slow cooker?

Yes. The same basic combination can be prepared on the stovetop, although the cooking time and liquid amounts will need to be adjusted because the slow cooker method is specifically designed for gentle cooking.

Can I use frozen peas?

Yes, but the recipe will have a slightly different texture. Canned peas are ideal for this version because their liquid contributes to the cooking mixture and helps create the nostalgic flavor and texture.

Can I add cheese?

Absolutely. Cheddar, American cheese, or another good melting cheese can turn this simple dish into a richer, cheesy macaroni and peas.

Is this recipe vegetarian?

As written, the recipe is vegetarian if the butter you use is vegetarian-friendly. Check the ingredients on your butter and any optional additions if this is important to you.

How do I make it more filling?
