Ingredients
- Olive oil and unsalted butter: provide a rich base for caramelizing onions and create a silky texture
- Yellow onions: are best for their natural sweetness and depth choose firm heavy ones with tight skins for the richest flavor
- Salt and black pepper: balance the sweetness of the onions and season each layer
- Fresh garlic: brings brightness and aromatic depth that lifts the sauce
- Red pepper flakes: add a gentle warmth without overwhelming spice
- Worcestershire sauce: delivers tang and umami complexity
- Reduced sodium soy sauce: deepens savoriness and enhances caramelization
- Water or beef broth: forms the liquid base with broth offering richer flavor if available
- Evaporated milk: creates creamy body with less fat than heavy cream
- Cornstarch: helps thicken the sauce so it clings perfectly to pasta
- Beef bouillon: intensifies savory notes but can be swapped for broth
- Fresh parsley and thyme: provide fresh herbal brightness dried versions work in a pinch
- Dried oregano and paprika: add earthy warmth and color
- Short cut pasta: such as orecchiette holds onto the sauce beautifully
- Gruyere cheese: melts with a nutty sweetness essential for French onion flavor
- Parmesan cheese: sharpens the finish with salty richness
- Fresh parsley for garnish: adds color and freshness at the end
Step by Step Instructions
- Caramelize Onions:
- Melt olive oil and butter in a Dutch oven over medium heat. Add sliced onions with a pinch of salt and pepper. Stir every few minutes and cook slowly until they turn deep golden brown and sweet about thirty to thirty five minutes. This step builds the foundation of flavor
- Make the Sauce:
- Stir in garlic red pepper flakes Worcestershire and soy sauce. Cook for about thirty seconds until fragrant to awaken flavors
- Add Liquids and Seasonings:
- Pour in water and half of the evaporated milk. Whisk cornstarch into the remaining evaporated milk until smooth then add to the pot. Stir in bouillon parsley thyme oregano paprika and black pepper. Raise heat and bring to a gentle boil blending flavors together
- Boil Pasta:
- Add uncooked pasta directly into the pot. Lower heat to a simmer and cook uncovered for twenty to twenty five minutes stirring often so it does not stick. Add water if needed to keep pasta covered and ensure tender cooking with some liquid left for sauce
- Add Cheeses:
- Take pot off the heat and stir in Gruyere a handful at a time allowing it to melt fully. Mix in Parmesan until sauce is velvety. Taste adjust seasoning and add a splash of milk or water if you want looser consistency. Garnish with fresh parsley before serving

Gruyere cheese is my favorite element with its nutty sweetness that transforms the dish. I once made it for a birthday dinner and my sister loved it so much she requested it every year after.
Storage Tips
Cool leftovers completely and store in an airtight container for up to four days in the fridge. Add a splash of milk or water to loosen sauce when reheating. Freeze portions for up to two months though cheese texture may change slightly after thawing.
Ingredient Substitutions
Swap Gruyere with Swiss or Emmental for similar nutty melt. Use vegetable or mushroom broth instead of beef for a vegetarian version. Penne or rotini can replace orecchiette if that is what you have.
Serving Suggestions
Serve with extra cheese or crispy shallots for crunch. Pair with a fresh green salad and crusty bread to balance richness. A glass of light red wine makes a lovely pairing.

Frequently Asked Questions About Recipes
- → What onions work best for this dish?
Yellow onions are the best choice since they caramelize into a rich sweetness. White onions can be used if you prefer a milder flavor.
- → Can I use another cheese instead of Gruyere?
Yes. Swiss or Emmental melt similarly with nutty depth, while Fontina adds creaminess. Parmesan balances with saltiness in the sauce.
- → How do I prevent the onions from burning?
Cook them low and slow over medium heat, stirring often. If they brown too fast, lower the heat and add a touch more butter or oil.
- → Is there a vegetarian option?
Yes. Replace beef bouillon with mushroom or vegetable broth. This keeps the umami depth while making the dish fully vegetarian.
- → Does this pasta reheat well?
It reheats beautifully. Add a splash of milk or water when warming on the stove or microwave to loosen the creamy sauce.
- → What pasta shapes are best?
Orecchiette, penne, rigatoni, or any short cut pasta works well since they hold onto the creamy sauce and onions.
