The internet has been going a little crazy for one-pan pastas lately.

You may have heard of the Baked Feta Pasta trend, which I’ll admit, is actually worth the hype.  I’ve adapted a few recipes based on that method and will be sharing one very soon (get excited).

But let’s start with this pasta, shall we?

I first learned about one-pan pasta when I worked for Martha Stewart.  To me, it originated with her.  This pasta isn’t baked, it’s made all on the stovetop.  No separate sauce pan, no straining.  The best part is that the creamy sauce has no butter, cream, or milk.  Instead, similar to risotto, it relies on frequent stirring and the starch that is extracted and developed to make it super creamy.

It uses so few ingredients, and such little water, and yet comes together quickly and beautifully every time.  It’s really a marvelous method.

One-Pan skillet spaghetti ingredients:

Spaghetti:  I like to use spaghetti for this, as I find it’s the perfect density to stand up to the sauce without being overpowered.  To keep it gluten free I use Jovial Foods Brown Rice Pasta or Banza Chickpea Pasta.  

Red onion:  I like the subtle sweetness that the red onion lends to the pasta, it’s a big part of flavoring the sauce.

Garlic:  Like onion, garlic is responsible for flavoring the sauce so it’s a must.  I slice it and the flavor melts into the pasta sauce, mellowing the slices as it cooks.  

“what else can i use?”

  • If you’re not gluten free, any spaghetti that you like will work here.  
  • I like spaghetti in this, but linguine is also great and it’s what Martha Stewart’s original recipe calls for.
  • Any size tomato can be used here, if you’re using cherry tomatoes simply halve them.  You want them to be in a 1 or 2 inch size.
  • Swap in kale, or even basil for the spinach if that’s what you have.  
  • You can make this recipe vegan simply by leaving out the parmesan at the end.

If you love pasta as much as me, and are looking for healthy and comforting ways to make it, be sure to also check out my Spicy Fusilli Pasta with Tomato + Cream.  It’s a favorite among all who make it!  As always, let me know what you think of this recipe – DM me on Instagram or share a photo of it to your stories so I can re-share.  I love to hear from you!

    So easy to make and so delicious. I added more spinach. I also pureed the tomatoes once they were cooked because my boyfriend prefers it that way.

    Made this for dinner tonight…absolutely delicious! I love that it’s so easy to prepare , and that it produces a creamy sauce without the use of butter or cream or milk. I’ll be making this again. Thanks!
