Step‑by‑Step Instructions for Creamy One-Pot French Onion Pasta
Step 1: Slice and Prepare Onions
Start by slicing three large yellow onions into thin, even strips. This preparation ensures they caramelize beautifully. Set the sliced onions aside as you gather your other ingredients and heat your cooking equipment.
Step 2: Sauté the Aromatics
In a large deep pan, heat 2 tablespoons of olive oil and 1/3 cup of butter over medium heat. Once the butter has melted and begins to bubble gently, add the sliced onions. Sauté for about 20 minutes, stirring occasionally, until they turn golden brown and develop a rich caramel color.
Step 3: Add Garlic and Seasonings
Stir in three minced garlic cloves along with a pinch of nutmeg and 1/4 teaspoon of black pepper. Continue to sauté for an additional 2 minutes, allowing the garlic to release its fragrant aroma and the flavors to meld together beautifully.
Step 4: Deglaze the Pan
Pour in 1/2 cup of dry white wine and 1 tablespoon of Worcestershire sauce to deglaze the pan. Use a wooden spoon to scrape up any browned bits stuck to the bottom, simmering the mixture for about 3–4 minutes until it reduces by half and thickens slightly.
Step 5: Cook the Pasta
Add 500 grams of your chosen pasta to the pan, along with 6.5 cups of low-sodium beef stock. Make sure the stock completely covers the pasta. Bring the mixture to a gentle simmer and keep an eye on it as you prepare for the next step.
Step 6: Cover and Simmer
Cover the pan with a lid and let it cook for 10–12 minutes. Stir occasionally to prevent sticking and make sure the pasta cooks evenly, until it is tender and most of the liquid has been absorbed.
Step 7: Stir in Cream and Cheese
Remove the pan from heat and stir in 1/2 cup of heavy cream, along with 1 cup of shredded Gruyère cheese and 1/2 cup of shredded Parmesan. Mix thoroughly until the cheeses are melted and the sauce becomes a creamy mixture that envelops the pasta.
Step 8: Serve and Garnish
Spoon the Creamy One-Pot French Onion Pasta into serving bowls and garnish with additional fresh thyme and a sprinkle of Parmesan cheese on top. This adds a lovely finish and enhances the dish’s comforting presentation.
Make Ahead Options
These creamy one-pot French onion pasta are perfect for meal prep enthusiasts! You can slice and sauté the onions up to 3 days in advance, storing them in an airtight container in the refrigerator to preserve their flavor and prevent browning. Additionally, you can measure out all the other dry ingredients and refrigerate the cheeses for quick access when it’s time to cook. When you’re ready to enjoy a comforting meal, simply combine the prepped components and follow the final steps—deglazing the pan, adding the pasta and stock, and finishing by mixing in the cream and cheeses. This method makes it easy to savor a homemade dish without the fuss on busy weeknights!
