This Easy French Onion Pasta is pure comfort food made simple all in one pot with no heavy cream required. It brings the nostalgic flavor of French onion soup together with creamy pasta that tastes like a hug on a gloomy day. The caramelized onions do all the heavy lifting so every bite is laced with rich flavor and no one would ever guess it comes together almost entirely from pantry staples.
The first time I made this, my family hovered, breathing in the smell of caramelized onions until I handed them bowls. Even my picky eater asked for seconds because it hits all the best cheesy and savory notes.
Ingredients
- Olive oil: Adds richness and helps caramelize the onions Pick a good quality extra virgin olive oil for best flavor
- Unsalted butter: Adds flavor depth along with the oil Use real butter for that classic French onion taste
- Large yellow onions: Sliced thin so they soften and sweeten as they cook Choose firm onions with tight skins
- Salt and pepper: Enhances and balances flavors Fresh cracked pepper makes a difference here
- Garlic cloves: Minced for punchy aromatics Look for plump cloves with no green center
- Red pepper flakes: Just a pinch for background warmth Use as much or as little as you like
- Worcestershire sauce: Adds a deep umami punch Go for a brand without artificial flavors if possible
- Reduced sodium soy sauce: Boosts savoriness while keeping salt in check Organic or traditionally brewed if available
- Water or beef broth: Your cooking liquid for everything Beef broth brings extra meaty flavor if you have it
- Evaporated milk: Creates creaminess without the weight of heavy cream Pick a can that isn’t expired check for dents
- Cornstarch: Helps the sauce cling to the pasta Clump free when whisked into milk first
- Beef bouillon: Adds concentrated beefy notes Skip this if you use beef broth instead
- Fresh parsley and thyme: Lift and brighten the finished dish Use fresh herbs if you can but dried will work in a pinch
- Dried oregano paprika and pepper: Build complex savory depth Make sure spices are fresh for best results
- Short cut pasta: Orecchiette or any shape that holds sauce works well Whole wheat or gluten free can be swapped in
- Gruyere cheese: Signature nutty meltiness from French onion soup style Freshly shred for the smoothest melt
- Parmesan cheese: Brings a sharp bite and creamy finish Grate right before using for best flavor
- Fresh parsley: Adds a pop of green and freshness Optional but pretty for serving
Step-by-Step Instructions
- Caramelize the Onions:
- Melt butter in olive oil in a large Dutch oven set over medium heat. Add the sliced onions along with salt and pepper. Stir well. Let the onions cook down slowly for thirty to thirty five minutes stirring occasionally until they turn deep golden brown. If they look like they are browning too fast lower the heat and drizzle in more oil or butter.
- Build the Sauce:
- After the onions are deeply caramelized stir in minced garlic and a pinch of red pepper flakes for about thirty seconds until fragrant. Add the soy sauce and Worcestershire sauce stirring to coat the onions so they soak up all that extra savory flavor.
- Add Liquids and Herbs:
- Pour in the water and half of your evaporated milk. In a small bowl whisk the cornstarch into the remaining evaporated milk until smooth. Add this slurry to the pot. Turn the heat up and stir in the beef bouillon parsley thyme oregano paprika and more black pepper. Bring everything to a full boil.
- Cook the Pasta:
- Once the mixture is boiling pour in the uncooked pasta. Stir to make sure all the pieces are submerged and covered in liquid. Reduce the heat to maintain a strong simmer and cook uncovered for twenty to twenty five minutes stirring often. If the mixture looks too dry add a bit more water as needed until the pasta is cooked al dente and there is some loose liquid left in the pot.
- Add the Cheeses:
- Remove your pot from the heat. Add the Freshly shredded Gruyere cheese in handfuls stirring after each addition until fully melted and the sauce is creamy. Sprinkle in the Parmesan and stir again. Taste and decide if you want more salt or pepper or a splash of water or milk for extra sauce. Garnish with chopped parsley if you like.

Gruyere is my favorite part of this recipe Its nutty melty texture takes me right back to the best bowls of French onion soup I shared with my sister when we tried making it from scratch one winter My kitchen always smells incredible while this simmers away on the stove

Ingredient Substitutions
If you need to avoid beef just use vegetable broth and skip the beef bouillon For a vegetarian version try Swiss cheese instead of Gruyere and double the Parmesan for a similar flavor Short cut gluten free pasta or whole wheat pasta can be swapped in For a dairy free spin use plant based butter and milk plus a little nutritional yeast in place of cheese
