- 30 g Butter (Unsalted)
- 30 ml Olive oil (A drizzle to prevent the butter from burning)
- 8 g All-purpose flour (To thicken the sauce)
- 5 g Sugar (A pinch to aid caramelization)

Instructions
Cooking the pasta
Bring a large pot of water to a boil, add the beef broth cube, lightly salt, then plunge the raw pasta. Cook about 10 minutes until al dente.
Time: PT10M
Temperature: high heat
Preparing the onions
Peel the yellow onions and coarsely slice them. To reduce tears, place the knife blade under a stream of water while cutting.
Time: PT10M
Grating the cheese
Grate the block of Comté (or Gruyère) into two parts: 150 g for the sauce, 50 g for the final gratin.
Time: PT5M
Caramelizing the onions
Melt the butter with a drizzle of olive oil in the pan over medium heat. Add the sliced onions, salt, pepper and cook gently, stirring continuously until they turn a beautiful golden color (15‑20 minutes). Add a pinch of sugar at the end of cooking to promote caramelization.
Time: PT20M
Temperature: medium heat
Thickening the sauce
Sprinkle the flour over the caramelized onions, stir quickly for 1 minute to cook the flour, then pour in the hot beef broth. Bring to a gentle boil, add the thyme, then incorporate the cooked pasta. Let simmer 5 minutes so the sauce coats the pasta.
Time: PT6M
Temperature: medium heat
Preparing the bread
Lightly brush each slice of country bread with a drizzle of olive oil, then rub each side with the crushed garlic clove for flavor.
Time: PT5M
Assembling the gratin
Pour the pasta‑onion mixture into the gratin dish, smooth the surface, sprinkle the first third of the grated cheese, place the bread slices on top, then add the remaining cheese.
Time: PT5M
Gratinating
Place the dish under the preheated oven grill and let it brown for 3‑5 minutes, until the cheese is melted and golden and the bread is crispy.
Time: PT5M
Temperature: 200°C (grill)
Serving
Remove the dish from the oven, let rest 2 minutes, then serve hot.
Time: PT2M
