One-Pot Creamy Shells & Cheese + 2-Ingredient Taco Mac Hack

Friends: I’m taking part in 30 Days of Gratitude on the Foodie With Family Facebook page. Join in when you can and share something you’re grateful for each day, or whenever you have a moment. It’s a simple way to spread thankfulness.

I’ll begin with a confession: I don’t like baked macaroni and cheese. Say what you will—texture is everything for me. Baked versions often miss the mark, but creamy, stove-top mac and cheese? That I love. Even better: shells and cheese. Mini pasta shells are endearing and do a fantastic job of holding sauce inside each little cup.

The trouble used to be the fuss—cooking pasta in one pot and making a separate béchamel in another felt messy. Then I discovered a game-changing idea: cook the pasta in the milk. It’s a simple shift that turns a two-pan chore into a one-pot miracle. As the pasta cooks, its starch thickens the milk into a saucy, creamy coating. Over the years I adjusted the technique and ingredients to fit my family’s tastes, and the version below is the one that reliably works for us.

This recipe is forgiving in some spots but strict in others. Follow these guidelines for consistent success:

Pick your milk. Use skim, 1%, 2%, or whole milk. The choice affects richness more than texture—pick the level of decadence you want.
Use small shells. This method was developed with small shells. Other pastas can behave differently; small shells produce consistent results every time.
Use a 50/50 cheese mix: Monterey Jack and extra-sharp Cheddar. Monterey Jack melts smoothly and is mild; sharp Cheddar gives tang. Together they create creamy, flavorful sauce.
Grate your cheese fresh. Pre-shredded cheese is coated to prevent clumping, which also prevents smooth melting. Grating your own yields a silkier result. Have the cheese ready before you start cooking.
Do not walk away from the pot. Stir almost continuously. The cooking pasta releases starch into the milk, thickening the sauce—and that same starch can stick and scorch if left unattended. Stirring keeps the sauce smooth and prevents scorching.

Now for a quick, delicious twist I call the Taco Mac Hack: top the finished creamy shells and cheese with warmed taco meat or browned Mexican-style chorizo and add a few candied jalapeños. If you like ketchup with mac and cheese, a spoonful of salsa also works. It’s an easy way to turn this meal into something fun and family-friendly.

One-Pot Creamy Shells and Cheese delivers creamy comfort in a single pan—perfect for quick weeknight dinners or whenever a rich mac and cheese craving hits. Includes an easy 2-ingredient Taco Mac Hack.

Ingredients

1 pound small shells pasta Do NOT use medium shells.
4 cups milk plus extra if needed
3 tablespoons butter
1/2 teaspoon ground mustard powder
2 teaspoons kosher salt
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1 cup grated Monterey Jack cheese
1 cup grated extra-sharp Cheddar cheese
freshly ground pepper to taste

Optional for Taco Mac:

Fully cooked taco meat or browned chorizo
Candied jalapeños

Instructions

Combine the small shells, milk, butter, mustard powder, salt, garlic powder, and onion powder in a large saucepan over medium heat. Stir almost constantly and be sure to scrape the bottom of the pan as you stir to avoid sticking. Slowly bring the mixture to a gentle simmer, then reduce the heat to low.
Continue stirring and simmering for about 15 minutes, or until the milk is mostly absorbed and the pasta is tender. If the pasta needs more time but the milk is nearly gone, add additional milk 1/4 cup at a time, allowing 3–5 extra minutes for the pasta to finish cooking.
Remove the pan from the heat and stir in the grated cheeses until melted and smooth.
Cover the pan and let it rest undisturbed for 3–5 minutes. Stir once more, season with freshly ground pepper to taste, and serve hot.
Store leftovers in an airtight container in the refrigerator. Reheat with a splash of milk in a saucepan or microwave to restore creaminess.
