Ingredients

Instructions

  1. Cook pasta: In a large pot, cook macaroni according to package directions. Drain and set aside.
  2. Caramelize onions: In the same pot, melt butter over medium heat. Add onions and cook 10–12 minutes until golden and soft. Add garlic and cook 1 minute.
  3. Make roux: Sprinkle flour over onions and stir 1 minute to cook.
  4. Add liquids: Gradually whisk in milk and beef broth. Bring to a simmer and cook 3–5 minutes until slightly thickened.
  5. Add cheese: Reduce heat to low. Stir in Gruyère and Parmesan until melted and smooth. Season with thyme, salt, and pepper.
  6. Combine: Stir in cooked pasta until well coated.
  7. Top: In a small bowl, mix panko with olive oil or melted butter. Sprinkle over the mac and cheese.
  8. Brown topping: Broil 2–3 minutes (watch closely!) until breadcrumbs are golden, or simply serve as-is.
  9. Serve hot! Great on its own or with a side salad.

Tip: For extra richness, stir in 1/4 cup cream cheese. Leftovers reheat beautifully with a splash of milk to restore creaminess.
