Ingredients You’ll Need

The magic of this recipe really comes from combining simple, fresh ingredients that complement each other perfectly. Each one plays a role in building that rich, layered flavor, and I always recommend choosing good-quality ingredients, especially the prosciutto and cheese.

• Salted butter: Helps caramelize the onions and adds richness; don’t substitute with margarine for best flavor.
• Yellow onions: Their natural sweetness caramelizes beautifully, so make sure to slice them thin and cook low and slow.
• Dry white wine: Pinot Grigio or Sauvignon Blanc works well to add acidity and brightness, balancing the richness.
• Garlic: Fresh chopped garlic enhances the savory depth without overwhelming the dish.
• Cremini or wild mushrooms: Adds earthiness and a meaty texture; slice evenly for even cooking.
• Fresh thyme leaves: Adds a subtle herbal note that pairs well with the onions and mushrooms.
• Fresh sage: Offers a slightly peppery, aromatic flavor to deepen the complexity.
• Low sodium chicken or vegetable broth: Provides the cooking liquid and layers of umami flavor; low sodium helps you control seasoning.
• Worcestershire sauce: Just a splash amps up umami and adds a touch of tanginess.
• Short cut pasta: Think penne, rigatoni, or similar – they hold sauce well and cook evenly in one pot.
• Kosher salt and black pepper: Essential for seasoning at every stage.
• Prosciutto: Tear it into pieces before baking to achieve those perfect, crispy shards.
• Heavy cream or milk: Cream makes it luscious; milk is a lighter option if you prefer.
• Gruyere cheese: Melts beautifully and adds a nutty sweetness to the sauce.
• Burrata cheese: Added at the end for creaminess and a fresh, tangy bite.

Variations

I love that this One Pot French Onion Pasta with Crispy Prosciutto Recipe is so adaptable to whatever you have on hand or your personal taste preferences. Feel free to play around with different herbs, cheeses, or even swap out the prosciutto for other cured meats or mushrooms if you want a vegetarian version.

• Vegetarian twist: Skip the prosciutto and add extra mushrooms or roasted chickpeas for texture – my family actually didn’t even miss the meat once!
• Cheese swaps: Try fontina or a sharp cheddar instead of Gruyere for a slightly different flavor profile.
• Herb variations: Rosemary or tarragon can replace sage for a fresh spin.
• Swap pasta shape: Penne, rigatoni, or shells all work if you can’t find short cut pasta; just adjust the cooking time slightly.

How to Make One Pot French Onion Pasta with Crispy Prosciutto Recipe

Step 1: Crisp Up the Prosciutto

Preheat your oven to 350°F and line a baking sheet with parchment paper. Tear the prosciutto into bite-sized pieces and lay them out in a single layer. Pop them in the oven for about 10-15 minutes until they’re beautifully crisp. I love this step because while the rest of the dish cooks, you get that perfect salty crunch to sprinkle on top at the end. Just keep an eye on them so they don’t burn!

Step 2: Caramelize the Onions Slowly

In your large Dutch oven or heavy-bottomed pot, melt the butter over medium-high heat. Add the thinly sliced yellow onions and stir occasionally as they soften over roughly 10 minutes. The trick I discovered is to add the white wine slowly—about 1/4 cup at a time—letting it absorb fully before adding more. This not only deglazes the pan but helps the onions caramelize deep golden brown and sweet. This step takes patience but trust me, it’s what transforms the dish.

Step 3: Build Flavor with Mushrooms, Herbs & Broth

Once your onions are rich and caramelized, stir in the garlic, sliced mushrooms, fresh thyme, and sage. Season with salt and pepper and cook for another few minutes until the mushrooms soften and the garlic is fragrant. Then pour in the remaining wine, the chicken or vegetable broth, Worcestershire sauce, and a pinch more seasoning. Crank the heat until it boils—this creates the perfect cooking liquid for your pasta.

Step 4: Cook the Pasta Right in the Pot

Add the short cut pasta directly into the boiling broth mixture. Stir frequently to keep the pasta from sticking and to ensure it cooks evenly. You’ll find that the pasta absorbs the broth and flavors while cooking, becoming tender and saucy in about 8-10 minutes. This method saves you from boiling and draining pasta separately and gives the dish an amazing texture.

Step 5: Finish with Cream, Gruyere & Burrata

Once your pasta is just al dente and the broth has mostly absorbed, stir in the heavy cream and shredded Gruyere cheese until melted and silky. Remove the pot from heat and gently break the burrata over the pasta, folding it in to create indulgent pockets of creaminess. Then top with your crispy prosciutto shards. This final layering of textures and flavors is why I call this a must-try One Pot French Onion Pasta with Crispy Prosciutto Recipe.

How to Serve One Pot French Onion Pasta with Crispy Prosciutto Recipe

Garnishes

I always finish this pasta with a little more fresh thyme or sage sprinkled on top—it brightens the rich flavors beautifully. If you have some extra burrata or shaved Gruyere on hand, adding a little more right before serving just elevates the luxurious feel. Sometimes I like a pinch of cracked black pepper or even a drizzle of good-quality olive oil to finish it off.

Side Dishes

This recipe is so rich and flavorful that simple sides work best for me. A crisp green salad with a vinaigrette cuts through the creaminess nicely, or you could roast some seasonal vegetables like asparagus or Brussels sprouts. Crusty bread is always a welcome side to mop up every last bit of sauce.

Creative Ways to Present

For a dinner party, I like to serve this pasta in individual shallow bowls with the crispy prosciutto artfully scattered on top. Adding a sprig of fresh thyme or sage on each plate adds a lovely touch. Another fun idea I’ve tried is serving it with a glass of the same white wine used in the dish, making it a seamless flavor experience.

Make Ahead and Storage

Storing Leftovers

Leftover pasta stores well in an airtight container in the fridge for up to 3 days. I recommend storing the crispy prosciutto separately so it stays crunchy, and adding it fresh when reheating. The flavors deepen after resting, so you might actually enjoy it even more the next day.

Freezing

I’ve frozen this pasta once or twice with decent results—just be sure to cool it completely and leave out the burrata, which can get a bit watery when thawed. Freeze in a freezer-safe container up to 2 months. When ready, thaw overnight in the fridge before reheating gently.

Reheating

To reheat, I prefer warming it on the stove over low heat with a splash of broth or milk to loosen the sauce. This helps maintain the creamy texture without drying out. Avoid the microwave if you want to keep it as close to fresh as possible, and always add the crispy prosciutto last to keep it crunchy.
