One-Pot Spaghetti with Sausage is the easiest and yummiest weeknight meal. All the ingredients are cooked together in one pot in under half an hour.

Some one-pot recipes are kind of a lie. They’ll tell you to make the sauce and add in cooked pasta. And I’m like, “But how do you cook the pasta?? In another pot!” Okay, I know I’m being dramatic, but if I’m making a one-pot recipe, I only want to use one pot!

Anyway, this is truly a one-pot recipe, with no need for another pot to boil the pasta. You make everything in the pot, then throw in the water and pasta and let it simmer for a bit and you’ll come out with a delicious dish.

How to Make One Pot Spaghetti

One-Pot Spaghetti is so simple to make. All you have to do is add everything into the pot all together and cook it until the pasta is cooked and the water has evaporated a bit. Well, it’s just a tiny bit more complicated than that, but this dish is an easy and quick version of traditional spaghetti.

First, you’ll cook the sausage and onion in a large pot in a little bit of olive oil. I like to use this meat chopper to break up the meat easily.

Next, cook the meat until it’s browned. If there is a lot of grease, you can strain it out with this silicone clip on strainer that I use all the time!

Add the broth to the pan and deglaze the pan. The bits stuck to the bottom of the pan have so much flavor that you don’t want them to be stuck to the pan but reincorporated into the sauce.

Add the marinara sauce, water, and spaghetti back to the pot and let simmer until it is all cooked through. Serve and garnish with grated parmesan.

What to Serve with One Pot Spaghetti

You could serve this dish by itself and it would be incredibly filling and comforting and wonderful, but if you’re looking to add some side dishes to this meal, you could serve this with steamed vegetables, a side salad, or some yummy garlic bread.

You could try my favorite Side Salad or my Garlic Pull Apart Rolls.

My Favorite One Pot Dinners

One-pot dinners are my saving grace on busy weeknights when it’s already past five and I haven’t even thought about what we’re going to have for dinner! I hate to say that happens far too often. Whenever I’m in that situation I whip up my favorite one-pot meals. Try any of these when you’re in a rush.
