Step-by-Step Instructions
- 1
Brown the ground beef in a large pot over medium-high until no longer pink, about 7 minutes; drain most of the fat. Add the onion and cook 3 minutes, then the garlic for 1 minute. Confirm the beef reached 160°F (71°C).
- 2
Add the marinara, beef broth, Italian seasoning, and red pepper flakes, and bring to a boil.
- 3
Add the broken spaghetti, pushing it into the liquid. Stir to separate the strands.
- 4
Reduce to a simmer and cook 12-15 minutes, stirring often, until the pasta is tender and the sauce has thickened.
- 5
Season to taste and let it rest 2-3 minutes to absorb a little more sauce.
- 6
Serve with Parmesan and basil.
Pro Tips for the Best Results
- Stir often in the first few minutes so the spaghetti doesn't clump or stick to the bottom.
- Breaking the spaghetti helps it fit and cook evenly in the pot.
- If the liquid reduces before the pasta is tender, add a splash more broth.
- Let it rest a couple minutes — the sauce thickens and clings as it stands.

How to Cook One-Pot Spaghetti
New to this dish? Follow along with the detailed guide below — we break down each stage so you get perfect results the very first time.
Brown the beef and build the sauce
Cook the beef to 160°F (71°C) and drain most of the fat, then soften the aromatics. Adding marinara plus extra broth creates the cooking liquid — the pasta will absorb it and become deeply flavored, unlike pasta boiled in plain water.
Cook the pasta in the sauce
Add the broken spaghetti to the boiling liquid and stir well to keep the strands separate. Frequent stirring in the first few minutes prevents clumping and sticking, which is the main thing to watch in a one-pot pasta.
Simmer and rest
Let it simmer until the pasta is tender and the sauce has reduced and thickened around it. A short rest off the heat lets the spaghetti soak up a bit more sauce, giving you a cohesive dish rather than a soupy one.
Storage & Make-Ahead
Refrigerate leftovers in an airtight container for up to 4 days; reheat with a splash of broth or water to loosen. Freezes well for up to 2 months.
Serving Suggestions
This one-pot spaghetti pairs beautifully with a crisp green salad, crusty bread, or your favorite grain. Add a simple side of roasted vegetables for a complete, satisfying dinner the whole family will enjoy.
Frequently Asked Questions
Why is my pasta sticking together?+
Stir frequently in the first 3-4 minutes and keep enough liquid in the pot so the strands move freely as they cook.
Can I make it vegetarian?+
Yes. Skip the beef, use vegetable broth, and add mushrooms or lentils for heartiness.
Can I use long, unbroken spaghetti?+
You can if your pot is wide enough to submerge it; let the ends soften for a minute, then push them in and stir.
