Easy One Pot Spaghetti
Disclosure: This post may contain affiliate links.
This easy one-pot spaghetti is a fast weeknight all-in-one meal. Ground beef is cooked with onion, mushrooms, and pasta in a spaghetti sauce.
No need to cook the pasta separately as it’s cooked along with the other ingredients!

Easy One-Pot Dinner
Spaghetti is an easy comforting meal that can feed the whole family with a few budget-friendly ingredients! Keep the extra pots clean as you can dump the pasta straight in and cook everything together. I love a simple, no-fuss dinner that’s family-friendly!
This spaghetti is cooked all together using simple, easy ingredients. I love 30-minute dinner ideas (like my ham cheese pasta casserole and one pan chicken burrito bowl) because they’re fast and filling!

Recipe Ingredients
LEAN GROUND BEEF: It’s my go-to for recipes like this one. It still has a little bit of fat for flavor, but not too much and will leave minimal grease that you’ll have to drain afterward. You could also use ground turkey or ground chicken!
SPAGHETTI SAUCE: Grab your favorite jar of spaghetti sauce from the grocery store and use that one. You’ll need a 22 oz (650 ml) jar. The entire jar will be added to the pot.
MUSHROOMS: I love to use canned mushrooms with my pasta sauces. This makes life easier, especially on busy weeknights. Just drain and dump them right into the pot. No washing and chopping are necessary.
PARMESAN CHEESE: This adds great flavor. A little is added to the meal, and then more can be sprinkled on individual plates once you’re serving.

How To Make One Pot Spaghetti
Once you make the pasta noodles with the spaghetti sauce, you may never look back! Learning this easy technique will save extra dishes and time!
- Brown the beef and onions in a pot.
- Add in all other ingredients according to the recipe instructions below.
- Cover and simmer until pasts noodles are tender.
- Sprinkle parmesan and mix in. Serve and enjoy!

Recipe Tips
- Break pasta into three sections. While it’s uncooked, use your hands to snap it into three sections. These will cook faster!
- Use canned mushrooms. Yes, fresh mushrooms always taste better. But we’re short on time and have had a long day! Save yourself that extra effort and just dump in the canned ones. No one will even notice!
- Add more water if needed. It will take 20-25 minutes for the pasta to cook to al dente. If the sauce reduces too much, you can add ½ cup of water and mix together. Cover and let it simmer another 2-3 minutes, then check the pasta again.
- Add more veggies! You can always add more vegetables to this recipe – fresh tomatoes, canned diced tomatoes, chopped bell pepper, asparagus, zucchini, corn and peas will all work. Try adding ½ cup to 1 cup depending on your preference. Any more will probably be too much.
