Cheesy Spaghetti is a quick and creamy weeknight meal the whole family will love!
author’s note
I Combined Their Two Favorite Dinners!
My kids are obsessed with spaghetti—they’d eat it every night if they could. And mac and cheese? Same.
So, I combined their two favorites into one super simple, cheesy spaghetti dish. I even tossed in some peas for a pop of color (and a little extra nutrition). They loved it, and I loved how quickly it came together. Honestly, it’s not much more time-consuming than making spaghetti with jarred sauce!
If your family loves cheesy pasta, this one is going to earn a permanent spot in your dinner rotation.

Ingredients
Here’s what you’ll need to make Cheesy Spaghetti:
| Ingredient | Tips & straightforward Swaps |
|---|---|
| Spaghetti | Cook just until al dente so it stays evenly tender after mixing with the sauce. Thin spaghetti also works. |
| Cheddar Cheese | Freshly grate it yourself for the smoothest, creamiest sauce. Sharp cheddar gives more flavor. |
| Frozen Peas | Add them during the last minute of cooking the pasta. Not a fan? Swap in broccoli, spinach, or finely diced steamed carrots. |
| Whole Milk | Whole milk creates the richest sauce, but 2% works too. Room-temp milk incorporates into the roux more smoothly. |
| Ground Mustard | It won’t make the pasta taste like mustard. It simply boosts the cheesy flavor and adds a little depth. |

How To Make Cheesy Spaghetti
- Cook Pasta: Boil spaghetti in salted water. Add peas in the last minute. Scoop out pasta water, then drain.
- Make Sauce: Melt butter, whisk in flour, then milk until thick.
- Season: Add garlic, onion, mustard powder, salt, and pepper.
- Add Cheese: mix in cheddar until melted.
- Combine: Toss pasta and peas in the sauce, adding pasta water if needed.
- Serve: Top with Parmesan and enjoy!

What To Serve With Cheesy Spaghetti
- French Bread: Classic and reliable for soaking up the creamy sauce.
- Side Salad: A crisp Caesar or my fave everyday salad adds balance.
- Roasted Veggies: Try broccoli, carrots, or asparagus.
- Grilled Chicken: Add protein for a heartier meal.
- Fruit: Anything in season or try a reliable fruit salad.
Storage
This cheesy spaghetti is best eaten fresh while creamy and smooth. For leftovers:
- Refrigerate: Keep in an airtight container for up to 2 days.
- Reheat: Add a little milk or water and warm on the stovetop or in the microwave, stirring often.
The sauce won’t be as creamy when reheated.
