A creamy, indulgent mac and cheese inspired by French onion soup, featuring caramelized onions, thyme, and a rich white cheddar sauce. Perfect as a main or side dish.

Ingredients

  • 8 oz elbow macaroni or pasta of choice
  • 2 large yellow onions, thinly sliced
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 1 tsp fresh thyme or 1/2 tsp dried thyme
  • 2 cloves garlic, minced
  • 2 tbsp all-purpose flour
  • 2 cups milk
  • 1/2 cup heavy cream (optional)
  • 1 1/2 cups shredded white cheddar cheese
  • 1/2 cup shredded Gruyère or mozzarella cheese (optional)
  • Salt and black pepper to taste
  • Optional: breadcrumbs for topping

Instructions

  1. Cook pasta according to package directions, drain, and set aside.
  2. In a large skillet, heat butter and olive oil over medium-low heat. Slowly caramelize onions with thyme and a pinch of salt for 25–30 minutes until golden and jammy, stirring frequently.
  3. Add minced garlic and cook for another minute.
  4. Sprinkle in flour and stir for 1–2 minutes to create a roux.
  5. Gradually whisk in milk (and cream if using) until smooth, then simmer until thickened.
  6. Reduce heat and stir in shredded cheeses until melted and creamy.
  7. Fold in the cooked pasta, coating evenly.
  8. Optional: Transfer to a baking dish, top with extra cheese or breadcrumbs, and broil for a few minutes until golden and bubbly.

Notes

  • Add shredded rotisserie chicken for a heartier meal.
  • Swap cheeses with fontina, Swiss, or Parmesan for different flavors.
  • Use gluten-free pasta and a gluten-free flour substitute like rice flour or cornstarch if needed.
  • Best eaten fresh, but leftovers reheat well with a splash of milk.
