Ingredients You’ll Need

Each ingredient in this One Pot French Onion Pasta brings something special to the table, from sweetness and richness to slurry-silky sauce and earthy balance. You probably have most of these on hand, and together they create a symphony of savory flavor!

• Olive oil: Used to slowly caramelize the onions, adding depth and richness to the entire dish.
• Yellow onions: The starring role—slice them thinly to maximize their sweet, mellow flavor during caramelization.
• Garlic: Minced fresh for a subtle, aromatic backbone that boosts everything.
• Cremini mushrooms: Bring a gentle earthiness and delightful texture, plus a touch of umami.
• Fresh thyme: Lends an unmistakable savory, herbaceous lift that’s classic with onions.
• Dry white wine: Helps deglaze the pan, picking up every bit of flavor and adding a sophisticated tang.
• All purpose flour: Just enough to thicken the sauce into luscious, coat-the-pasta velvet.
• Beef broth (or vegetable broth): Makes the sauce soulfully savory—choose vegetable for a meatless version.
• Water: Keeps the consistency just right so the pasta cooks evenly in the pan.
• Dried orecchiette or other short cut pasta: Orecchiette “cups” soak up the sauce beautifully, but any sturdy short pasta works great.
• Sherry vinegar: The finishing splash that brightens flavors at the very end.
• Salt and freshly ground black pepper: Season to taste—these punch up the savory notes and give you control over the dish’s balance.
• Fresh herbs and toasted breadcrumbs: Optional, but offer an irresistible color, freshness, and crunch if you want to take your bowl over the top!

Variations

One Pot French Onion Pasta is endlessly customizable, making it easy to tweak for whatever you’ve got in the pantry or whatever you crave most tonight. Don’t be afraid to riff and make it your own—this recipe welcomes adventurous swaps and clever tweaks!

• Make it vegetarian: Use vegetable broth in place of beef broth, and consider stirring in a handful of baby spinach at the end for extra color and nutrients.
• Cheesier, please: Top with shredded Gruyère or mozzarella and broil the pot briefly for a bubbling, golden cheese crust à la classic French onion soup.
• Swap the mushrooms: Not a fan of mushrooms? Try diced bell peppers, zucchini, or even a handful of peas for a different twist.
• Gluten-free option: Use your favorite gluten-free pasta and a 1:1 gluten-free flour blend so everyone at your table can enjoy a bowl.

How to Make One Pot French Onion Pasta

Step 1: Caramelize Your Onions

Start by heating the olive oil in your biggest skillet or Dutch oven over medium heat. Add the thinly sliced onions and a generous pinch of salt. Let them cook low and slow, stirring frequently, until they’re golden brown and meltingly soft—this takes about 25-30 minutes. The transformation is magical: patient cooking here brings out every bit of their gentle sweetness and savory depth.

Step 2: Sauté the Flavor Makers

Stir in the garlic, cremini mushrooms, and fresh thyme. Sauté for 3-4 minutes, just until the mushrooms give up some of their moisture and start to soften. This step layers in the earthy, fragrant notes that define the best French onion soups.

Step 3: Deglaze and Thicken

Pour in the dry white wine, making sure to scrape up any caramelized bits on the bottom of the pan—these are pure flavor heaven! Once the wine has mostly evaporated, sprinkle in the flour and let it cook for a couple of minutes, stirring the whole time, until everything thickens up nicely.

Step 4: Simmer the Sauce and Cook Your Pasta

Now, pour in the broth and water, season the pot with salt and pepper, and bring the sauce to a gentle boil. Once bubbling, add the dried pasta straight in—no pre-cooking necessary! Let everything cook together, stirring occasionally, until the pasta is just al dente (usually 8-10 minutes, but check your pasta for doneness).

Step 5: Brighten and Serve

Take the pan off the heat and stir in the sherry vinegar. This last flourish wakes everything up and echoes classic French onion soup. Serve steaming bowls as-is for comfort food at its best, or sprinkle with fresh herbs and toasted breadcrumbs to bring color and crunch.

Garnishes

Side Dishes

This pasta is hearty enough to shine solo, but it plays beautifully with a sharply dressed green salad or warm, crusty baguette for true French bistro vibes. A simple arugula salad with lemon vinaigrette or roasted asparagus makes a perfect partner, cutting through the rich sauce.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Reheating
