The creamy onion sauce doubles as a natural gravy, making any plate richer and more comforting.

Ingredients (Serves 4)

• 2 pounds yellow onions (about 4–5 medium), sliced into 1/2-inch rings
• 2 cups whole milk
• 3 tablespoons unsalted butter, cut into pieces
• Salt and black pepper (optional, to taste)

Directions

2. Slice onions into thick rings and spread evenly in the dish.
3. Season lightly with salt and pepper (optional).
4. Dot with butter pieces, distributing evenly over onions.
5. Pour milk over onions until they are nearly covered.
6. Cover tightly with foil and bake for 45 minutes.

9. Let rest for 10 minutes before serving to allow sauce to thicken.
