Ingredients
  

  • 1 medium eggplant
  • 2 medium zucchinis
  • 1 yellow squash optional, for color
  • 1 red bell pepper
  • 1 yellow bell pepper
  • 4 medium ripe tomatoes
  • 1 medium onion sweet if possible
  • 3 garlic cloves minced
  • 2 tbsp olive oil
  • 1 tsp salt adjust to taste
  • Freshly ground black pepper
  • 1 tsp dried thyme
  • 1 tsp dried oregano
  • 1 sprig fresh rosemary
  • A handful of fresh basil leaves chopped
(Optional: Goat cheese or Parmesan for serving)

Method
 

Step 1 – Make the base sauce
  1. Heat 1 tbsp olive oil in a skillet.
  2. Add chopped onion, cook until soft.
  3. Stir in garlic, red and yellow peppers, and cook for 5 minutes.
  4. Add 2 chopped tomatoes, thyme, oregano, salt, and pepper.
  5. Simmer until thick and saucy. Spread this sauce into the bottom of a baking dish.
Step 2 – Slice the vegetables
  1. Slice eggplant, zucchini, yellow squash, and the rest of the tomatoes into thin rounds, about 1/8-inch thick.
Step 3 – Layer the ratatouille
  1. Arrange the slices in a circular pattern over the sauce, alternating eggplant, zucchini, squash, and tomato.
  2. Keep the slices snug, like roof shingles.
Step 4 – Season and bake
  1. Drizzle the last tablespoon of olive oil on top.
  2. Add chopped basil and fresh rosemary.
  3. Cover with parchment paper cut to the shape of your dish.
  4. Bake at 375°F (190°C) for 40–45 minutes, until vegetables are tender.
Step 5 – Serve bistro-style
  1. Serve warm with crusty bread, rice, or salad. Add goat cheese on top if you like.

Notes

  • Use firm, ripe vegetables for the best texture.
  • You can double the base sauce if you like a saucier ratatouille.
  • Leftovers taste even better the next day as flavors blend together.
  • If you don’t like eggplant, swap with extra zucchini or mushrooms.
