Ingredients & Instructions
Here’s everything you need to make this rich, comforting one-pot meal, along with tips to get every step just right.
Ingredients
For the Onions:
- 3 tablespoons olive oil
- 2 tablespoons unsalted butter
- 3 large yellow onions, sliced into 1/8-inch rings (mandoline recommended)
- 1/8 teaspoon salt
- 1/8 teaspoon black pepper
For the Sauce:
- 4 garlic cloves, minced
- Pinch to 1/4 teaspoon red pepper flakes
- 1 tablespoon Worcestershire sauce
- 1 tablespoon reduced-sodium soy sauce
- 5 1/2 cups water (or substitute beef broth)
- 1 12-oz can evaporated milk
- 1/2 tablespoon cornstarch
- 2 tablespoons beef bouillon (optional if using beef broth)
- 1 tablespoon fresh parsley, minced (or 1 teaspoon dried)
- 2 teaspoons fresh thyme, minced (or 3/4 teaspoon dried)
- 1/2 teaspoon dried oregano
- 1/2 teaspoon paprika
- 1/2 teaspoon black pepper
Add Last:
- 1 pound short-cut pasta (orecchiette recommended)
- 5 oz freshly shredded Gruyere cheese
- 1/4 cup freshly shredded Parmesan cheese
- Fresh parsley for garnish (optional)
Step-by-Step Instructions
1. Caramelize the Onions
In a large 7-quart Dutch oven, melt the butter in the olive oil over medium heat. Add the sliced onions, salt, and pepper.
Cook slowly, stirring occasionally, until the onions are deeply golden and caramelized—this should take 30–35 minutes. If the onions start to brown too fast or stick, reduce the heat or add a bit more oil or butter.
Tip: Uniform slices ensure even caramelization, so a mandoline or sharp knife is your best friend here.
2. Make the Sauce
Once the onions are deeply caramelized, add the garlic, red pepper flakes, soy sauce, and Worcestershire sauce. Cook for 30 seconds until fragrant.
Add water and half of the evaporated milk. In a small bowl, whisk the cornstarch with the remaining evaporated milk, then stir it into the pot.
Mix in the beef bouillon, parsley, thyme, oregano, paprika, and black pepper. Bring the mixture to a boil.
3. Cook the Pasta
Add the pasta to the boiling liquid. Reduce heat to a medium-high simmer and cook for 20–25 minutes, stirring often to prevent sticking and ensure the pasta remains submerged. Add more water if the liquid absorbs too quickly before the pasta is al dente.
Tip: Stirring frequently near the end is key to preventing the pasta from sticking to the bottom and to evenly distribute flavors.
4. Add the Cheeses
Remove the pot from heat. Stir in the Gruyere cheese handful by handful until fully melted, followed by the Parmesan cheese.
Garnish with fresh parsley if desired. Serve immediately for best results—creamy, cheesy, and deeply flavorful.
Cooking Tips & Variations
1. Enhance Your Veggies
Add sautéed mushrooms, roasted vegetables, or cooked meat for extra texture and flavor.
2. Cheese Swaps
If you don’t have Gruyere, try Swiss, Provolone, Gouda, or Fontina. These all melt beautifully and provide unique flavor profiles.
3. Dairy-Free Option
Replace evaporated milk with unsweetened almond or oat milk and skip the cheese, or use dairy-free cheese alternatives.
4. Vegetarian Version
Use vegetable broth instead of water/beef broth and a vegetarian Worcestershire sauce.
5. Leftover Tips
Store in an airtight container in the fridge for up to 5 days. Reheat with a splash of water or milk to bring back the creamy texture.
Storage & Serving Suggestions
Storage:
- Refrigerator: 4–5 days in an airtight container.
- Reheating: Warm in a skillet or microwave, adding a splash of liquid to maintain creaminess.
Serving Suggestions:
- Serve with a fresh green salad or steamed vegetables to balance the richness.
- A side of crusty bread or garlic bread is perfect for soaking up any leftover sauce.
