Step-by-Step Instructions for the Ultimate Veggie Bake

Follow these steps for a flawless, flavorful result:

Prep & Mix

  1. Preheat and Prepare
    Preheat your oven to 375°F (190°C) and lightly spray a 12×16-inch baking sheet with non-stick cooking spray. Even oil coverage helps the dish release easily once baked.
  2. Veggie Layering
    In a large bowl, combine:
    • Thin zucchini slices
    • Sliced red onion
    • Packed baby spinach
  3. Add Flavor & Texture
    Quarter the drained sun-dried tomatoes and toss them in with:
    • Pine nuts
    • Fresh basil
    • 1 Tbsp thyme
    • Salt and pepper
      Stir gently so your veggies are well coated.
  4. Dry Mix
    In a separate bowl, whisk together flour, cornmeal, and baking powder—then add it to your veggie mixture.

Batter & Bake

  1. Sweeten & Bind
    Beat the eggs with sugar, then fold into the veggie-flour mix—even distribution ensures your bake sets beautifully.
  2. Oil Blend
    Add enough olive oil to the reserved tomato oil to make one full cup, pour into the bowl, and stir through.
  3. Add Water
    Slowly stir in water until a thin batter forms. Don’t overdo it; you just need a pourable consistency.
  4. Spread & Drizzle
    Spread the mixture evenly onto the baking sheet, drizzle olive oil over the top, and bake for 55–60 minutes, until golden and set.

Final Touches

  1. Cheese & Herbs
    Once out of the oven, sprinkle Parmesan, a drizzle of olive oil, and the remaining 1 tsp thyme.
  2. Serve
    Slice into 12 squares. Serve warm, at room temp, or chilled—you can even pack it for lunch or bring it to your next potluck.

Tips for the Best Zucchini and Sun-Dried Tomato Bake

  1. Combat Zucchini Wateriness
    Salt the slices and let them rest 10–15 minutes; blot any excess moisture before mixing—this prevents soggy casserole.
  2. Unlock More Flavor
    Lightly toast pine nuts until golden. This step adds depth and avoids bitterness.
  3. Rest Before Slicing
    Allow the bake to cool for 10–15 minutes after baking. This helps it set and keeps your squares intact.
  4. Store Smartly
    Keep leftovers in an airtight container in the fridge for up to 4 days.
  5. Meal Prep & Freeze
    Slice into portions, wrap in foil, and freeze for up to 3 months—perfect for easy reheating.

Variations and Substitutions

Customize to Your Taste or Dietary Needs

  • Nut-free: Replace pine nuts with pumpkin or sunflower seeds.
  • Gluten-free: Use a certified gluten-free baking mix in place of flour/cornmeal.
  • Cheese swap: Try feta or goat cheese instead of Parmesan.
  • Vegan version: Use flaxseed “eggs” (1 Tbsp ground flax + 3 Tbsp water per egg) and vegan cheese.
  • Flavor variations: Stir in roasted bell peppers or mushrooms for extra richness.
