Ingredients:

140 grams (10 tablespoons) unsalted butter, divided
2 small yellow onions, thinly sliced
2 cloves garlic, minced
2 teaspoons fresh thyme leaves, minced
1 bay leaf
60 ml (1/4 cup) dry sherry or white wine
2 teaspoons beef bouillon paste
2 teaspoons Worcestershire sauce
454 grams (1 pound) uncooked pasta shells
946 ml (4 cups) whole milk
60 grams (1/2 cup) all-purpose flour
226 grams (2 cups) shredded sharp cheddar cheese
340 grams (3 cups) shredded mozzarella cheese

Directions:

In a medium saucepan over low heat, melt 28 grams (2 tablespoons) of butter. Add the onions, garlic, thyme, and bay leaf, and cook until the onions are caramelized, about 35 minutes.
Increase the heat to high and add the sherry, cooking for 1 minute while scraping up any browned bits. Stir in the beef bouillon and Worcestershire sauce, then remove from heat and discard the bay leaf. Set aside.
In a large pot of salted boiling water, cook the pasta until al dente, about 10 minutes. Drain and set aside.
In a medium saucepan over medium heat, warm the milk until simmering, then set aside.
In a large heavy-bottomed stockpot over medium heat, melt the remaining 112 grams (8 tablespoons) of butter. Whisk in the flour and cook, whisking constantly, until light brown and aromatic, about 3 minutes.
Slowly whisk in the warm milk, continuing to whisk constantly to avoid lumps. Cook until thick enough to coat the back of a spoon, about 2 minutes.
Reduce the heat to medium and stir in the cheddar and mozzarella cheeses until melted and smooth.
Add the cooked pasta to the cheese sauce, stirring to combine. Fold in the onion mixture until evenly distributed. Serve hot and enjoy the luxurious flavors of French Onion Mac and Cheese!

Notes:

For added depth of flavor, you can substitute red wine for the sherry.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave before serving.
