How to Make Cheesy Pasta Caramelized Onions

Here is exactly how we make these cheesy pasta caramelized onions: about 10 minutes of prep and roughly 40 minutes of cooking.

What you need: Large Skillet, Large Pot, Oven, Whisk.

1. Melt butter in olive oil in a large Dutch oven over medium heat.
2. Add the onions, salt, and pepper.
3. Cook, stirring occasionally, until onions are caramelized and dark golden brown, about 30 to 35 minutes.
4. Once the onions are caramelized, add the garlic, red pepper flakes, soy sauce, and Worcestershire sauce and cook for 30 seconds.
5. Add the water and half of the evaporated milk.
6. Whisk the cornstarch with the remaining evaporated milk and add to the pot.
7. Increase heat to high to bring to a boil while stirring in the beef bouillon and remaining herbs and seasonings.
8. Once boiling, add the pasta and reduce to a simmer over medium-high heat for 20 to 25 minutes or until al dente, stirring often.
9. Once the pasta is done cooking, it should still have some excess liquid.
10. Remove the pan from the heat and stir in the Gruyere cheese a handful at a time until melted, followed by the Parmesan until melted.
11. Taste and season with salt and pepper if desired.
12. If you would like a saucier pasta, stir in additional water or milk.

Variations and Add Ins

Cheesy pasta caramelized onions takes changes well, so treat the recipe above as a starting point rather than a set of rules. These are the swaps we come back to most often.

• Change the shape. Anything with ridges or curves holds this sauce well.
• Add protein. Chicken, beef or shrimp turn it into a full dinner.
• Sneak in vegetables. Spinach, peas or broccoli stir in at the end with no fuss.
• Make it lighter. Half and half in place of cream keeps it silky with less richness.
• Change the herbs. Fresh parsley, basil or dill at the end each send it somewhere slightly different for no extra effort.
• Make it a bigger meal. Serve it over rice or with warm bread and it stretches to feed another person or two.

Change one thing at a time rather than three. That way you find out what you actually like in this dish instead of guessing at the end.

How to Store and Reheat Cheesy Pasta Caramelized Onions

Leftovers keep in an airtight container in the refrigerator for up to three days. Pasta drinks up sauce as it sits, so add a splash of broth or cream when you reheat it and stir until it loosens up again.

If you are cooking ahead on purpose, prep the components and keep them separate until you are ready. It takes a few minutes off a busy evening and the recipe holds its texture far better that way.
