Let’s Make it together
Prepare Your Ingredients: Start by gathering all your ingredients on the counter. Chop your onions thinly and mince the garlic; have everything ready for cooking.
Sauté Those Onions: In a large skillet over medium heat, add olive oil and let it warm up before tossing in the sliced onions. Cook until they turn golden brown and smell heavenly—around 15-20 minutes.
Add Garlic and Broth: Once those onions are perfectly caramelized, stir in minced garlic for about 1 minute until fragrant. Pour in vegetable broth and let it simmer gently.
Create That Creamy Sauce: Lower the heat and stir in heavy cream along with freshly grated parmesan cheese. Mix until everything is well combined—your sauce will be silky smooth!
Cook Your Pasta: Boil your fettuccine or spaghetti according to package instructions until al dente. Reserve some pasta water before draining—it’s liquid gold!
Toss Together & Serve: Add drained pasta into the skillet with sauce, mixing thoroughly while adding reserved water if needed for consistency. Adjust seasoning with salt and pepper before serving hot!
This delightful caramelized onion pasta is not just another meal; it’s an experience filled with laughter and rich flavors waiting to become part of your culinary story!
