How to Make Caramelized Onion Pasta
First, prepare the pasta. Bring a large pot of salted water to boil before adding your chosen pasta. Cook according to package instructions until al dente, then drain and set aside.
Next, let’s dive into those onions! In a large skillet over medium heat, add olive oil and sliced yellow onions. Stir occasionally until they soften and start turning golden brown—this usually takes about 15-20 minutes.
Once they start caramelizing, add minced garlic to the skillet. Sauté for another minute until fragrant; you’ll know it’s ready when your kitchen smells like heaven.
Now it’s time for some liquid magic! Pour in vegetable broth and let it simmer gently while scraping up those tasty bits stuck to the pan. This step usually takes about five minutes, allowing flavors to meld beautifully.
Add heavy cream next! Stir it in slowly while watching it transform into a creamy delight. Let everything simmer for an additional few minutes until the sauce thickens slightly.
Finally, toss in grated Parmesan cheese. Mix well until everything is combined into one glorious pasta masterpiece. Season with salt and pepper as needed; don’t be shy—taste as you go!
Serve your caramelized onion pasta immediately! Garnish with extra Parmesan or fresh herbs if you wish. Enjoy each bite as you savor both its comforting warmth and complex flavors that dance on your palate like a waltz at a fancy ball.
