1. Boil water: Bring a large pot of salted water to a rolling boil. Add 12 oz spaghetti (or any pasta of your choice) and cook according to package instructions until al dente. Once done, drain and set aside.
2. Sauté onions: In a skillet, heat 2 tablespoons of olive oil over medium heat. Add the 2 large, thinly sliced onions and cook, stirring occasionally, for about 15-20 minutes until they become golden brown and beautifully caramelized.
3. For the Sauce: Add garlic: Toss in the 3 cloves of minced garlic to the caramelized onions and cook for an additional 1-2 minutes until fragrant. Pour in 1 cup of heavy cream (or half-and-half) and stir to combine. Season with 1 teaspoon salt and 1/2 teaspoon black pepper to taste.

Tips for the Best caramelized onion pasta
- Onion Selection: Use sweet onions like Vidalia or Walla Walla for a richer flavor that enhances your caramelized onion pasta.
- Perfect Caramelization: Stir occasionally but not too often; letting them sit helps develop that golden-brown color and deep flavor.
- Cream Consistency: For a lighter sauce, use half-and-half instead of heavy cream; just be cautious not to boil it too rapidly to prevent curdling.
- Season Gradually: Taste and adjust salt and pepper after adding the cream; flavors can intensify during cooking, so start light.
- Pasta Timing: Ensure your spaghetti is al dente before mixing with the sauce; overcooked pasta will become mushy in the caramelized onion pasta dish.
How to Store and Freeze caramelized onion pasta
- Fridge: Store leftover caramelized onion pasta in an airtight container for up to 3 days to maintain freshness.
- Freezer: For longer storage, freeze the pasta in a freezer-safe container for up to 2 months.
- Reheating: Thaw in the fridge overnight, then reheat on the stove over medium heat with a splash of cream for added moisture.
- Garnish: Add fresh parsley just before serving; store it separately to keep it vibrant and fresh.

How do I know when my onions are properly caramelized?
Caramelizing onions takes time, around 15-20 minutes over medium heat. You’re looking for a deep golden brown color and a sweet aroma. Stir them occasionally to prevent sticking and burning; they should be soft and slightly translucent when done.
Can I make this dish dairy-free?
Absolutely! To make your caramelized onion pasta dairy-free, simply replace the heavy cream with a plant-based alternative such as coconut cream or cashew cream. Also, consider omitting the parmesan cheese or substituting it with a dairy-free cheese option to keep the flavors intact.
How should I store leftovers of caramelized onion pasta?
If you have any leftovers, store them in an airtight container in the refrigerator. They should stay fresh for up to 3 days. When you’re ready to enjoy again, reheat gently on the stovetop over low heat, adding a splash of water or extra cream if necessary to loosen the sauce.

What can I do if my sauce is too thick?
If you find that your sauce has thickened too much after combining with the pasta, don’t worry!
