Essential Ingredients

Here’s what you’ll need to make this delicious dish:

Pasta: Use any type you love; I usually opt for fettuccine for its ability to hold sauce beautifully.
Onions: Sweet onions work best; they bring out the natural sugars when caramelized.
Garlic: Fresh garlic adds an aromatic punch that complements the sweetness of the onions.
Olive Oil: Extra virgin olive oil gives richness and depth; it’s worth using quality oil here.
Vegetable Broth: Use low-sodium broth to control saltiness while adding flavor during cooking.
Cream or Vegan Cream Alternative: For a luscious finish; choose based on dietary preferences.
Parmesan Cheese (optional): A sprinkle of cheese elevates the dish’s flavor—use nutritional yeast for a vegan option.
Fresh Herbs (optional): Basil or parsley brightens up the dish with freshness—don’t skip this!

Let’s Make it Together

Sautéing Onions to Perfection: Begin by heating olive oil over medium heat in a large skillet. Add thinly sliced onions and cook until they soften and turn golden brown, about 15-20 minutes.

Add Garlic and Flavor Up!: As your onions reach that beautiful caramel color, toss in minced garlic. Sauté until fragrant—about 1-2 minutes—being careful not to burn it.

Pasta Time!: In another pot, cook your chosen pasta according to package directions until al dente. Reserve some cooking water before draining—trust me on this one!

Create Creamy Sauce Magic!: Pour vegetable broth into the skillet with onions and garlic; let it simmer for about 5 minutes. Then stir in cream or vegan alternative until everything blends beautifully.

Mix It All Together!: Add drained pasta into the skillet, tossing gently to coat every strand in that rich sauce. If needed, add reserved pasta water gradually until you achieve your desired consistency.

Finishing Touches!: Season generously with salt and pepper. Sprinkle fresh herbs if you’re feeling fancy; serve hot with optional grated Parmesan on top!

This recipe is so simple yet delivers layers of flavor that will leave you dreaming about it long after dinner is over! Enjoy each cheesy bite as you savor all those sweet notes from the caramelized onions!
