Ingredients for One Pot French Onion Pasta
- 3 large yellow onions, thinly sliced
- 3 tablespoons butter or olive oil
- 3 cloves garlic, minced
- 1 teaspoon dried thyme (or fresh if available)
- ½ teaspoon salt, plus more to taste
- ½ teaspoon black pepper
- 1 teaspoon sugar (helps with caramelization)
- 6 cups beef broth (or vegetable broth for a lighter version)
- 8 oz pasta (penne, rotini, or your favorite short pasta)
- ¼ cup heavy cream or half-and-half
- 1 to 1½ cups shredded Gruyère or Swiss cheese (or mozzarella for milder flavor)
- Fresh parsley or chives for garnish
Step-by-Step Instructions
1. Caramelize the Onions
Heat butter or olive oil in a large deep skillet or Dutch oven over medium heat. Add the sliced onions and sprinkle with sugar and salt. Cook slowly, stirring frequently, until the onions turn a deep golden brown and caramelized. This process takes about 20-25 minutes but is key for building that rich, sweet flavor.
2. Add Garlic and Thyme
Once the onions are beautifully caramelized, add minced garlic and dried thyme. Stir and cook for another 1-2 minutes until fragrant.
3. Add Broth and Pasta
Pour in the beef broth and bring to a gentle boil. Add your pasta and reduce heat to a simmer. Cover partially and cook according to pasta package instructions, usually 10-12 minutes, stirring occasionally to prevent sticking. The pasta will absorb the flavorful broth as it cooks.
4. Stir in Cream and Cheese
When the pasta is tender and most of the broth is absorbed, reduce the heat to low. Stir in the heavy cream and shredded cheese. Mix until the cheese melts into a creamy, luscious sauce that coats the pasta perfectly.
5. Adjust Seasoning and Serve
Taste and add more salt or pepper if needed. Garnish with fresh parsley or chives for a pop of color and fresh flavor. Serve immediately while warm and gooey.
Tips for the Best French Onion Pasta
- Patience with Onions: Take your time caramelizing the onions—they are the flavor foundation.
- Use Good Broth: A rich beef broth gives authentic French onion flavor, but vegetable broth works well too.
- Cheese Choices: Gruyère is classic for French onion soup, but Swiss, mozzarella, or even fontina work great.
- Add Mushrooms: For extra earthiness, sauté mushrooms with the onions.
- Protein Boost: Add cooked chicken, sausage, or crispy bacon to make it a heartier meal.
Variations to Try
- Vegetarian: Use vegetable broth and add mushrooms or spinach for extra veggies.
- Cream-Free: Skip the cream and finish with a touch of butter and extra cheese for a lighter version.
- Gluten-Free: Substitute regular pasta for gluten-free pasta varieties.
- French Onion Mac & Cheese: Bake the cheesy pasta in a casserole dish topped with breadcrumbs for a crispy crust.
