What Is French Onion Pasta?
French Onion Pasta is a pasta-based dish inspired by the flavors of classic French onion soup. Instead of bread and broth, the deeply caramelized onions are paired with pasta and a creamy, cheesy sauce. Gruyère cheese—traditionally used in French onion soup—adds nuttiness and depth, while Parmesan enhances the savory notes.
Unlike traditional cream-based pasta dishes, French Onion Pasta (Creamy One-Pot, No Heavy Cream) relies on evaporated milk and starch from the pasta itself to create a luscious sauce that feels indulgent without being overly rich.

Ingredients Breakdown
For the Onions

Yellow onions: The star of the dish—yellow onions caramelize beautifully and develop natural sweetness.
-
Salt & black pepper: Enhances the onion flavor and draws out moisture for better caramelization.
For the Sauce
-
Garlic: Adds aromatic depth.
-
Red pepper flakes: Optional, but great for a subtle heat.
-
Worcestershire sauce & soy sauce: These bring umami and complexity without overpowering the dish.
-
Water or beef broth: Forms the base of the sauce.
-
Evaporated milk: Creates creaminess without heavy cream.
-
Cornstarch: Helps thicken the sauce gently.
-
Beef bouillon: Intensifies the savory flavor—this is key to that “French onion” taste.
-

Step-by-Step Instructions
1. Caramelize the Onions
Heat olive oil and butter in a large Dutch oven over medium heat. Add the sliced onions, salt, and pepper. Cook slowly for 30–35 minutes, stirring occasionally, until the onions are deeply golden and caramelized.
This step is non-negotiable—the onions are the backbone of French Onion Pasta (Creamy One-Pot, No Heavy Cream). If they start browning too quickly, reduce the heat or add a little more oil or butter.
2. Build the Flavor
Add garlic, red pepper flakes, Worcestershire sauce, and soy sauce. Stir and cook for about 30 seconds, just until fragrant.
3. Make the Sauce
Pour in the water (or broth) and half of the evaporated milk. Whisk the cornstarch into the remaining evaporated milk, then add it to the pot. Increase heat to high and bring to a boil. Stir in the beef bouillon, herbs, and seasonings.
4. Cook the Pasta
Once boiling, add the pasta. Reduce to a steady simmer and cook 20–25 minutes, uncovered, stirring often so nothing sticks. The pasta should be al dente, with enough liquid remaining to form a creamy sauce. Add more water if needed.
5. Finish with Cheese
Remove from heat. Stir in Gruyère cheese a handful at a time until melted, then add Parmesan. Taste and adjust seasoning. If you want a looser sauce, add a splash of water or milk. Garnish with parsley if desired.
Tips for Success
-
Low and slow onions: Rushing this step will cost you flavor.
-
Use freshly shredded cheese: Pre-shredded cheese doesn’t melt as smoothly.
-
Stir often once pasta is added: This prevents sticking and ensures even cooking.
-
Adjust consistency at the end: Pasta thickens as it sits—add liquid as needed.
Flavor Variations & Add-Ins
One of the best things about French Onion Pasta (Creamy One-Pot, No Heavy Cream) is how adaptable it is.

Why Evaporated Milk Works So Well
Evaporated milk is simply milk with about 60% of its water removed. It’s richer than regular milk but lighter than heavy cream. When combined with cornstarch and pasta starch, it creates a sauce that’s creamy, stable, and reheats beautifully—perfect for a one-pot pasta like this.
