Instructions
1. Preheat the Oven
Heat your oven to 375°F. Proper heat helps tomatoes cook evenly and breadcrumbs turn golden.
2. Prepare the Baking Dish
Brush the baking dish with olive oil. This prevents sticking and adds extra flavor.
3. Slice the Tomatoes
Cut tomatoes into thick slices. Thick slices hold shape and release less water while baking.
4. Slice the Onion
Slice the onion thinly. Thin slices soften nicely and blend with the tomatoes.
5. Make the Base Layer
Place half the tomatoes in the baking dish. Add half the onions on top evenly.
6. Add Garlic and Herbs
Sprinkle minced garlic and fresh herbs over the layer. This builds flavor early.
7. Season Lightly
Add salt and black pepper. Season gently because cheese adds salt later.
8. Repeat the Layers
Add remaining tomatoes and onions. Repeat garlic, herbs, and seasoning.
9. Prepare the Topping
Mix breadcrumbs with grated cheese and olive oil in a bowl until well coated.
10. Add the Topping
Spread the breadcrumb mixture evenly over the tomatoes. Cover the surface fully.
11. Bake the Gratin
Place dish in the oven. Bake for 40 to 45 minutes until bubbling and golden.
12. Rest Before Serving
Let the gratin rest for 10 minutes. This helps flavors settle and slices hold.
