14 Pasta Recipes That Start with Just Onion and Garlic

I keep coming back to onions and garlic as the foundation for my favorite pasta dishes. These two ingredients create magic in your kitchen – they build deep flavors that transform simple sauces into memorable meals. From classic marinara to creamy mushroom pasta, these 14 recipes show you how versatile this aromatic duo can be.

My travels through Italy taught me that the best pasta starts with simple, quality ingredients. Each recipe here builds on that wisdom, adding fresh vegetables, herbs, and seasonings to create distinctive sauces. You’ll find global influences too, from North African harissa to Caribbean coconut milk, proving that pasta knows no borders.

These recipes make cooking from scratch both practical and enjoyable. I’ve included options for every season – light pesto for summer, butternut squash sauce for fall, and hearty lentil bolognese for winter nights. The best part? Most ingredients are probably sitting in your pantry right now. Start with onion and garlic, and watch your pasta transform.

Marinara Sauce

I start by sautéing chopped onions and garlic in olive oil until golden brown and fragrant. Then I add crushed tomatoes, dried herbs like oregano and basil, plus a pinch of salt and pepper. After simmering for 20 minutes, the sauce transforms into a rich, thick marinara that coats pasta beautifully.

This versatile sauce goes beyond just pasta – spread it on homemade pizza, use it as a dipping sauce for breadsticks, or spoon it over roasted vegetables. You can even freeze portions to have an instant sauce ready for quick weeknight dinners.

Serve this comforting pasta dish with a crisp arugula salad dressed in lemon vinaigrette. For extra crunch, add some toasted pine nuts on top and finish with fresh parsley. A side of crusty garlic bread makes an ideal companion to soak up every last drop of the silky sauce.
