Ingredients for French Onion Mac and Cheese Recipe

- Butter
- Cavatappi or favorite macaroni noodle
- All-purpose flour
- Milk
- Fontina, Gruyere and sharp white cheddar cheese
- Dijon mustard
- Cayenne pepper
- Fresh thyme leaves
How to Make French Onion Macaroni and Cheese
In a large skillet, melt 3 tablespoons of butter.
Once the butter has fully melted, add in your sliced Peri & Sons Farms® Premium White Onion and pinch of salt. Allow it to cook over medium-low heat until caramelized, about 30 minutes.
Cook pasta according to package directions until al dente. Drain the pasta.
While the pasta and onions are cooking, place 2 tablespoons of butter in a large pan over medium-high heat. Once the butter has melted, add in the flour and stir until combined. Allow the flour to cook off for about 1 minute.
While using a whisk, slowly pour in the milk. Bring to a boil and reduce to medium heat. Simmer and stir until the sauce has thickened, about 5-6 minutes.
Stir in the fontina, cheddar and 1 cup of gruyere cheese until the cheese has melted.
Remove from the heat and add in the pasta, caramelized onions, cayenne, dijon, and thyme.
Divide the mixture into 8 ramekins or a baking dish that has been pre-greased. Top with the remaining gruyere. Bake for about 20 minutes until the sauce is bubbly around the edges.
To get the cheese golden brown, place under the boiler for about 2 minutes. Feel free to serve with fresh thyme!
