Ingredients
  

  • Ripe tomatoes sliced
  • Yellow onion thinly sliced
  • Garlic cloves minced
  • Olive oil
  • Fresh basil leaves
  • Fresh thyme or parsley
  • Breadcrumbs
  • Grated Gruyère or Parmesan cheese
  • Salt
  • Black pepper
  • These are the main Ingredients for Ina Garten Tomato Gratin. Fresh ingredients give the best result.

Instructions
 

Preheat the Oven

  • Heat your oven to 375°F. Proper heat helps tomatoes cook evenly and breadcrumbs turn golden.

Prepare the Baking Dish

  • Brush the baking dish with olive oil. This prevents sticking and adds extra flavor.

Slice the Tomatoes

  • Cut tomatoes into thick slices. Thick slices hold shape and release less water while baking.

Slice the Onion

  • Slice the onion thinly. Thin slices soften nicely and blend with the tomatoes.

Make the Base Layer

  • Place half the tomatoes in the baking dish. Add half the onions on top evenly.

Add Garlic and Herbs

  • Sprinkle minced garlic and fresh herbs over the layer. This builds flavor early.

Season Lightly

  • Add salt and black pepper. Season gently because cheese adds salt later.

Repeat the Layers

  • Add remaining tomatoes and onions. Repeat garlic, herbs, and seasoning.

Prepare the Topping

  • Mix breadcrumbs with grated cheese and olive oil in a bowl until well coated.

Add the Topping

  • Spread the breadcrumb mixture evenly over the tomatoes. Cover the surface fully.

Bake the Gratin

  • Place dish in the oven. Bake for 40 to 45 minutes until bubbling and golden.

Rest Before Serving

  • Let the gratin rest for 10 minutes. This helps flavors settle and slices hold.

Notes

  • Use Roma tomatoes for less water.
  • Sprinkle sugar lightly if tomatoes lack sweetness.
  • Add mozzarella for extra melt.
  • Use gluten-free breadcrumbs if needed.
  • Add zucchini slices for variety.
  • Fresh basil on top adds color and aroma.
