French Onion Soup Pasta Ingredients
For the Pasta

• Salt – A pinch enhances the flavors of the entire dish; be mindful of your broth’s salt content.
For the Onion Mixture
• Yellow Onions – The heart of the dish; three large onions provide the perfect caramelized flavor.
• Unsalted Butter – Helps achieve the perfect caramelization; it’s best to use this for deeper flavors.
• Fresh Thyme – Adds that aromatic touch; dried thyme can work in a pinch if fresh isn’t available.
• Salt and Pepper – Basic seasonings to elevate the taste of your French Onion Soup Pasta.
For the Broth
• Beef Broth – Infuses depth into the dish; low-sodium options let you control the saltiness.
• Vegetable Broth – Swap in for a vegetarian version without compromising the comforting essence.
For the Topping
• Gruyère Cheese – An essential for that gooey, cheesy top; fresh shreds offer the best melt.
• Swiss or Mozzarella – These can be used in place of Gruyère if needed for a different flavor profile.
Step‑by‑Step Instructions for French Onion Soup Pasta
Step 1: Caramelize the Onions
In a large pot, melt 4 tablespoons of unsalted butter over medium heat. Once melted, add 3 sliced large yellow onions with a pinch of salt. Cook for 20-25 minutes, stirring occasionally, until the onions are golden brown and caramelized, releasing a sweet, inviting aroma. This is the heart of your French Onion Soup Pasta.
Step 2: Add the Broth and Herbs
Pour in 4 cups of low-sodium beef broth and add a few sprigs of fresh thyme to the caramelized onions. Bring the mixture to a gentle simmer and let it cook for about 10 minutes. This step allows the flavors to meld together beautifully, creating a rich, savory base for your pasta.
Step 3: Cook the Pasta
While the broth simmers, fill a separate pot with salted water and bring it to a boil. Add your favorite wide pasta, such as pappardelle, and cook it according to package instructions until al dente, usually around 8-10 minutes. Remember to reserve about a cup of the starchy pasta water before draining the noodles.
Step 4: Combine the Pasta and Onion Mixture
Once the pasta is ready, add it directly to the pot with the onion and broth mixture. Stir well to combine, allowing the pasta to soak up the delicious flavors. If the mixture looks too thick, gradually add some reserved pasta water until you reach your desired consistency for the French Onion Soup Pasta.
Step 5: Prepare for Broiling
Preheat your broiler to high while you transfer the pasta mixture to an oven-safe dish. Evenly sprinkle 2 cups of shredded Gruyère cheese on top, ensuring it covers the pasta completely. The cheese will melt and create a delightful, gooey topping that’s essential for this recipe.
Step 6: Broil the Cheese Topping
Place the dish under the broiler for about 3-5 minutes or until the cheese is bubbly and golden brown. Keep a close eye on it to prevent burning. Once it’s reached that perfect, crispy finish, remove the dish from the oven and let it cool slightly before serving.
Step 7: Serve and Enjoy
Scoop generous portions of your French Onion Soup Pasta onto each plate, enjoying the cheesy, savory goodness. Pair it with a crisp salad or some crusty bread for a full meal experience. The comforting flavors are sure to impress everyone at the table!

Expert Tips for French Onion Soup Pasta
-
Perfect Caramelization: Stir the onions frequently and cook over medium heat to prevent burning, ensuring they turn a beautiful golden brown.
-
Quality Cheese Matters: Use freshly grated Gruyère for the best melt and flavor. Pre-shredded varieties often contain anti-caking agents that can hinder melting.
-
Vegetarian Option: For a vegetarian French Onion Soup Pasta, simply substitute beef broth with vegetable broth and avoid meat toppings without losing depth of flavor.
-
Adjust Consistency: If your pasta mixture is too thick after combining, add small amounts of reserved pasta water until you achieve your desired consistency.
-
Cooling Time: Let the pasta cool slightly after broiling, this allows flavors to meld beautifully and prevents burns while serving.
Make Ahead Options
These French Onion Soup Pasta are perfect for busy weeknights and meal prep! You can caramelize the onions and prepare the broth up to 24 hours in advance, storing them separately in airtight containers in the refrigerator. For best flavor retention, refrigerate the onions right after cooking to prevent browning. Additionally, you can cook your pasta and toss it with a bit of olive oil to prevent sticking before storing it in the fridge for up to 3 days. When you’re ready to serve, simply combine the pasta with the onion mixture, broil with cheese until bubbly, and enjoy a comforting meal that tastes just as delicious as when first made!
