Ingredients

• 12 ounces penne pasta
• 4 medium yellow onions
• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 1 teaspoon fresh thyme leaves
• 1 teaspoon granulated sugar
• 1 teaspoon sea salt
• 0.5 teaspoon black pepper
• 1.5 cups Fontina cheese
• 0.5 cup heavy cream
• 0.25 cup grated Parmesan cheese
• 2 tablespoons chopped parsley
• 4 quarts water
• 1 tablespoon salt (for boiling pasta)

Directions

Step 1

Bring 4 quarts of water to a boil in a large pot. Add 1 tablespoon of salt and the penne pasta. Cook until al dente according to package instructions. Reserve 1/2 cup of the pasta cooking water, then drain the rest and set the pasta aside.

Step 2

While the pasta cooks, peel and thinly slice the yellow onions.

Step 3

In a large skillet over medium heat, melt the butter and olive oil together. Add the sliced onions, thyme, and granulated sugar. Cook, stirring occasionally, for 25-30 minutes until the onions are deeply golden and caramelized.

Step 4

Season the caramelized onions with sea salt and black pepper. Stir and remove the skillet from heat.

Step 5

In a small saucepan over low heat, warm the heavy cream. Gradually add the shredded Fontina cheese, stirring until smooth and melted. Remove from heat once combined.

Step 6

Add the cooked penne pasta to the skillet with the caramelized onions. Pour the cheese sauce over the pasta and toss to coat. If the sauce is too thick, add a splash of the reserved pasta cooking water to loosen it.

Step 7

Stir in the grated Parmesan cheese and heat everything through over low heat for 1-2 minutes.

Step 8

Garnish the pasta with chopped parsley before serving warm.
