Dana Lesniewski


5 Tbs. butter, divided, plus more room temperature for brushing
2 large yellow onions, thinly sliced
salt to taste
8 oz. cavatappi or other short curly pasta
2 Tbs. flour
2½ c. whole milk
1 c. grated fontina cheese
2½ c. grated Gruyere cheese
1 c. shredded sharp white cheddar cheese
1 tsp. dijon mustard
pinch of cayenne pepper
½ tsp. thyme

1. Preheat oven to 350°. Brush 4 to 6 ramekins (depending on size) or small ovenproof baking dishes with butter. Alternatively, brush one large baking dish with butter.
2. In a large skillet, melt 3 tablespoons of the butter over medium. Add the onions and a pinch of salt and cook, stirring occasionally, until they are golden, about 30 minutes.
3. Cook pasta in a large pot of boiling salted water, following package directions until al dente. Drain pasta.
4. In a medium saucepan, melt the remaining 2 tablespoons butter over medium-high. Add flour and cook, stirring, 1 minute. While whisking, slowly pour in milk until combined. Bring to a boil and reduce heat to medium. Simmer, stirring, until sauce is thickened, about 6 minutes. Stir in fontina, 1 cup of the gruyere, and cheddar until cheese is melted. Remove from the heat. Stir in the pasta, caramelized onions, Dijon, thyme, and cayenne. Season with salt and pepper.
5. Divide mixture among ramekins and top each ramekin with the remaining gruyère. Bake until sauce is bubbly around the edges, about 20 minutes.
6. Switch oven to broil and broil until cheese is golden, about 2 minutes. Garnish with more thyme before serving.
