How to Make One Pot French Onion Pasta
-
Melt butter and olive oil in a large Dutch oven over medium heat. Let the combination shimmer before adding your sliced onions, salt, and pepper to enhance their flavor.
-
Cook the onions, stirring occasionally, until they are beautifully caramelized and reach a dark golden brown, about 30-35 minutes. Patience is key here—watch them transform!
-
Add minced garlic, red pepper flakes, Worcestershire sauce, and soy sauce to the pot. Cook for 30 seconds, allowing the garlic to release its aromatic essence into the mix.
-
Pour in the water and half of the evaporated milk. In a separate bowl, whisk the cornstarch with the remaining evaporated milk and then add it to the pot. Raise the heat to high to bring the mixture to a boil while stirring in the beef bouillon and your choice of herbs and spices.
-
Stir in the short cut pasta once the mixture is boiling. Reduce the heat to a simmer over medium-high heat and cook for 20-25 minutes, stirring often to ensure the pasta is submerged in the delicious liquid.

One Pot French Onion Pasta Recipe FAQs
What kind of onions should I use for One Pot French Onion Pasta?

Store your leftover pasta in an airtight container in the refrigerator for up to 3 days. Make sure it’s completely cooled before sealing it to avoid trapping steam, which can create sogginess.
