Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large ovenproof skillet over medium-high heat. Sauté onion, garlic, and bell pepper for 3 minutes until softened. Add eggplant and zucchini; cook for 5 minutes until slightly browned.
  2. Step 2: Stir in diced tomatoes, oregano, salt, and pepper. Cook for 2 minutes until tomatoes begin to break down. Add sliced yellow squash and top with fresh basil.
  3. Step 3: Cover skillet with a lid and transfer to a preheated 375°F (190°C) oven. Bake for 25-30 minutes until vegetables are tender and sauce has thickened.
  4. Step 4: Remove lid and cook uncovered for 5 more minutes to evaporate excess liquid. Let rest for 10 minutes before serving to allow flavors to meld.

Total time is about 60 minutes (25 min prep + 35 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep medium zucchini (sliced) from drying out.

Can I substitute ingredients in Herb Garden Ratatouille?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut).

How do I scale Herb Garden Ratatouille for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
