Step‑by‑Step Instructions for Simple Caramelized Onion Pasta
Step 1: Heat the Oils
In a large skillet, combine 2 tablespoons of olive oil and 2 tablespoons of butter, setting the burner to low-medium heat. Allow the fats to melt and become fragrant, swirling to combine, this should take about 2 minutes. The warmth will prepare the skillet for the onions, yielding a rich base for your Simple Caramelized Onion Pasta.
Step 2: Sauté the Onions
Add 2 thinly sliced onions to the skillet, stirring them gently to coat in the oil and butter. Lower the heat and let the onions slowly caramelize, stirring occasionally for about 20 minutes. Keep an eye on them, waiting for their color to turn deep golden-brown, releasing a sweet, aromatic scent that signals they are perfectly cooked.
Step 3: Add Heat and Cream
Once the onions are beautifully caramelized, drizzle in 1 tablespoon of chili oil to introduce a spicy flair, stirring well. Then pour in 1 cup of heavy cream, followed by 1 teaspoon of garlic powder, and season with salt and pepper. Let this mixture simmer gently for 5 minutes, allowing the flavors to meld into a luxurious sauce for the pasta.
Step 4: Cook the Pasta
While the sauce simmers, bring a pot of salted water to a boil, and cook your favorite pasta according to package instructions until al dente. After draining, save about ½ cup of the pasta water before adding it directly into the skillet with the sauce. This will ensure a creamy texture that clings beautifully to the pasta.
Step 5: Combine and Simmer
Add the cooked pasta to the skillet, tossing it gently to coat evenly in the caramelized onion sauce. Turn up the heat to medium-high and let it simmer together for a few minutes, stirring frequently to ensure every piece is enveloped in that rich flavor. The sauce should thicken, creating a delightful creamy finish.
Step 6: Garnish and Serve
Once the pasta is well coated and heated through, remove the skillet from heat and sprinkle chopped fresh parsley over the dish for a touch of brightness. Allow it to cool for a minute, then serve immediately, enjoying the warm embrace of this comforting Simple Caramelized Onion Pasta as a perfect weeknight meal.
