Ingredients
-
8 ounces penne pasta
-
¼ cup olive oil
-
8 shallots, thinly sliced
-
5 garlic cloves, thinly sliced
-
1 teaspoon kosher salt, plus more for the pasta water
-
2 tablespoons balsamic vinegar
-
¾ cup grated Gruyere cheese
-
Black pepper, to taste
Instructions
-
Cook the Pasta: Bring a large pot of salted water to a boil. Add the penne and cook according to package instructions, about 10 minutes, or until al dente. Drain, reserving ½ cup of pasta water.
-
Caramelize the Shallots: While the pasta cooks, heat the olive oil in a large sauté pan over low heat. Add the sliced shallots and cook for about 15 minutes, stirring occasionally. Add the salt after the first 5 minutes and continue cooking until the shallots are soft and caramelized.
-
Add the Garlic: Stir in the sliced garlic and cook for another 2 minutes until fragrant.
-
Deglaze with Balsamic Vinegar: Add the balsamic vinegar and cook for about 30 seconds, stirring to coat the shallots and garlic.
-
Combine the Pasta and Cheese: Add the drained pasta and grated Gruyere to the pan. Toss until the cheese begins to melt and coats the pasta.
-
Adjust the Consistency: Slowly stir in reserved pasta water, a little at a time, until the sauce reaches your preferred consistency.
-
Season and Serve: Add black pepper and adjust the salt to taste. Serve immediately while creamy and warm.
Notes
-
Cook the shallots slowly: Low heat helps bring out their natural sweetness without burning them.
-
Slice evenly: Thin, consistent shallot slices cook more evenly and soften beautifully.
-
Reserve pasta water: Its starch helps the cheese form a smoother sauce that clings to the pasta.
-
Add cheese gradually: Stir it into the warm pasta to help it melt evenly.
-
Watch the garlic: Add it after the shallots soften to prevent it from burning during the longer cooking process.
