Ingredients for One Pot French Onion Pasta

Gathering your ingredients is the first step to unlocking this amazing French Onion Soup Pasta One Pot experience. You’ll need:

2 tablespoons unsalted butter – this is key for getting those onions perfectly caramelized
2 large yellow onions, thinly sliced – patience here is rewarded with deep flavor
3 cloves garlic, minced – for that classic aromatic base
1 teaspoon dried thyme – it complements the onion flavor beautifully
1/2 teaspoon salt – to enhance all the savory notes
1/4 teaspoon black pepper – just a touch for a little warmth
8 ounces uncooked penne pasta – or your favorite short pasta shape
3 cups low-sodium vegetable broth – the liquid gold that cooks the pasta
1 cup water – to ensure the pasta cooks evenly
1 cup shredded Gruyère cheese – for that signature melty, nutty goodness
1/4 cup grated Parmesan cheese – adds a salty, sharp finish
Fresh parsley, chopped (for garnish) – for a pop of color and freshness

How to Make One Pot French Onion Pasta

Step 1: Begin by preheating your oven to 375°F (190°C). While the oven heats, melt the 2 tablespoons unsalted butter in a large pot or Dutch oven over medium heat. Add the 2 large yellow onions, thinly sliced, and cook them, stirring occasionally. You’re looking for a deep, golden-brown caramelization, which usually takes about 20-25 minutes. This slow caramelization is crucial for that authentic French onion flavor.
Step 2: Once your onions are beautifully caramelized, add the 3 cloves garlic, minced, 1 teaspoon dried thyme, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Stir everything together and cook for another 1-2 minutes until the garlic is fragrant. The kitchen will start to smell amazing!
Step 3: Now, it’s time to add the pasta and liquids. Stir in the 8 ounces uncooked penne pasta, 3 cups low-sodium vegetable broth, and 1 cup water. Give it a good stir to make sure all the pasta is submerged. Bring this mixture to a boil.
Step 4: Once boiling, reduce the heat to a simmer. Let it cook uncovered, stirring occasionally to prevent sticking. Continue cooking until the pasta is perfectly al dente and most of the liquid has been absorbed, which should take about 10-12 minutes. This is where the magic happens for a truly quick One Pot French Onion dinner.
Step 5: Remove the pot from the heat. Sprinkle in the 1 cup shredded Gruyère cheese and 1/4 cup grated Parmesan cheese. Stir gently until the cheeses are completely melted and you have a wonderfully creamy, cheesy sauce coating the pasta. This step truly elevates your quick One Pot French Onion dinner.
Step 6: Serve your delicious One Pot French Onion Pasta immediately. Garnish with fresh chopped parsley for a burst of color and freshness. This is truly a quick One Pot French Onion dinner that will impress everyone!

Pro Tips for the Best One Pot French Onion Pasta

Want to elevate your One Pot French Onion Pasta game? Here are a few tricks I’ve picked up that make all the difference:

Don’t rush the onion caramelization; it’s the foundation of that deep French onion flavor. Low and slow is the way to go!
Use good quality broth. Since it’s one of the main liquids, a flavorful broth really shines through.
Taste and adjust seasoning before serving. Pasta can absorb a lot of salt, so a final check ensures perfect balance.
If you have time, letting the cooked pasta sit in the creamy sauce for a few minutes before serving allows the flavors to meld even more.

How do I avoid common mistakes with One Pot French Onion Pasta?

A common pitfall is not caramelizing the onions enough, which leads to a less flavorful dish. Also, be careful not to overcook the pasta; it should be al dente.
