Table of Contents

This 3-ingredient mac and cheese recipe needs only pasta, cheese, and dairy. No flour or roux required. The one-pot stovetop method cooks pasta directly in milk. Starch from the pasta thickens the sauce naturally. Grate your own cheese for smoothest results. Pre-shredded contains anti-caking agents that ruin texture. Use full-fat dairy like whole milk, evaporated milk, or heavy cream. Pull pasta slightly underdone. Add cheese off the heat to prevent separation. Total cook time is 15 minutes. Customize with hot sauce, mustard powder, bacon, or vegetables after mastering the basic technique.

Question

Answer

Can I use pre-shredded cheese for mac and cheese?

No, pre-shredded cheese contains anti-caking agents that prevent smooth melting and create grainy texture.

Why add cheese off the heat?

High heat causes cheese to separate and become greasy, so removing from heat ensures a smooth sauce.

What dairy works best for creamy mac and cheese?

Evaporated milk creates the thickest, creamiest sauce, but heavy cream and whole milk also work well.

How do I fix grainy cheese sauce?

Grainy sauce comes from overheating cheese, so always melt cheese off the heat with constant stirring.

Should pasta be fully cooked before adding cheese?

No, cook pasta just shy of al dente since it continues cooking in the hot sauce.

The Three Ingredients You Need for Mac and Cheese

Homemade mac and cheese with 3 ingredients strips away the complexity. No flour. No roux. No béchamel sauce. Just pasta, cheese, and dairy.

Pasta

Elbow macaroni is the classic choice. Other shapes work too. Cavatappi, shells, penne, rotini all grab sauce well. Bronze-cut pasta works best. The rough texture helps cheese sauce stick.

Cheese

Cheddar is the go-to. Sharp or mild, your choice. Freshly grated cheese melts better than pre-shredded bags. Pre-shredded contains anti-caking agents that affect texture.

Other good melting cheeses:

  • Gruyère
  • Monterey Jack
  • Fontina
  • Muenster

Mix cheeses for more complex flavor. A combination of cheddar and Gruyère creates depth.

Dairy

The liquid ingredient determines creaminess. Each option creates different results.

Dairy Option

Result

Evaporated milk

Ultra-creamy, thick sauce

Heavy cream

Rich, indulgent

Half and half

Medium richness

Whole milk

Lighter, still creamy

Full-fat dairy is essential. Low-fat milk won't create the same silky texture. The fat helps the cheese emulsify into a smooth sauce.

Salt and pepper don't count as ingredients. Season to taste at the end.

Step by Step Stovetop Method

The one-pot method is fastest. Everything cooks in a single pot. No draining required.

Ingredients

  • 8 oz elbow macaroni
  • 2 cups whole milk or evaporated milk
  • 2 cups freshly grated cheddar cheese

Instructions

Place pasta and milk in a medium saucepan or high-sided skillet. Add a pinch of salt. Bring to a boil over medium-high heat.

Reduce heat to medium. Stir frequently to prevent sticking. Cook until pasta is just shy of al dente, about 7-8 minutes. The liquid will reduce and thicken from pasta starch.

Remove from heat. Stir in cheese a handful at a time. Keep stirring until completely melted and smooth. The sauce will continue thickening off the heat.

Taste. Add salt and pepper as needed. Serve immediately for creamiest texture.

Alternative Heavy Cream Method

Cook pasta separately in salted water. Drain and return to pot. Add 1 cup heavy cream. Place over low heat. Slowly stir in grated cheese until melted and smooth.

Step

Time

Boil milk and pasta

2-3 minutes

Simmer until al dente

7-8 minutes

Melt in cheese off heat

2-3 minutes

Total time

15 minutes

Stir constantly once you add cheese. This prevents clumping and ensures a silky sauce.

Tips for the Creamiest Sauce Every Time

Creamy sauce comes down to technique. Follow these rules for perfect results every time.

Grate Your Own Cheese

Pre-shredded cheese contains cellulose and anti-caking agents. These prevent smooth melting. Buy block cheese and grate it yourself. Takes 30 seconds. Makes a huge difference.

Use Full-Fat Dairy

Skip low-fat milk. The fat content helps cheese emulsify properly. Whole milk at minimum. Heavy cream or evaporated milk works best for ultra-creamy results.

Pull Pasta Early

Cook pasta just shy of al dente. It keeps cooking in the hot sauce. Overcooked pasta gets mushy and releases too much starch.

Common Problems and Fixes

Problem

Cause

Fix

Grainy sauce

Cheese overheated

Melt cheese off heat

Thin sauce

Too much liquid

Cook longer to reduce

Clumpy cheese

Added too fast

Add gradually, stir constantly

Separation

High heat

Use low heat, be patient

Temperature Matters

Add cheese off the heat. High heat makes cheese separate and get greasy. Remove pot from burner. Let it sit 30 seconds. Then stir in cheese.

  • Stir constantly when melting cheese
  • Add cheese in small batches
  • Wait for each batch to melt before adding more
  • Serve immediately for best texture

Salt your pasta water well. Season the sauce at the end. Taste before serving.

Easy Variations and Add-Ins

The basic 3-ingredient recipe works great on its own. Add a few extras to change things up.

Flavor Boosters

These add flavor without counting as extra ingredients. Keep them in your pantry.

  • Hot sauce - adds subtle heat
  • Mustard powder - enhances cheese flavor
  • Dijon mustard - 1/2 teaspoon works wonders
  • Garlic powder - savory depth
  • Paprika - mild smokiness
  • Black pepper - classic finish

Protein Add-Ins

Turn mac and cheese into a complete meal. Stir these in at the end.

Protein

Prep

Bacon

Cook until crispy, crumble on top

Chicken

Use rotisserie or leftover cooked

Ground beef

Brown separately, drain, stir in

Ham

Dice and add cold or warm through

Vegetable Mix-Ins

Add nutrition and color. Quick options that cook fast.

  • Broccoli florets - steam separately
  • Peas - frozen, stir in at end
  • Spinach - fresh leaves wilt in hot pasta
  • Kale - chopped, cooks in minutes

Cheese Combinations

Try different cheese blends for new flavors. A 2 cheese mac and cheese adds complexity. Mix sharp cheddar with Gruyère for depth. Pepper Jack brings heat. Monterey Jack melts smoothly.

For a baked version with crispy top, try this simple homemade baked mac and cheese recipe. Transfer cooked mac to a baking dish. Top with buttered breadcrumbs. Broil 2-3 minutes until golden.
