📝 Ingredients

(Serves 6)

  • 3–4 medium zucchinis (~6 cups diced)

  • 2 tbsp butter

  • 1 small onion, finely chopped

  • 2 large eggs

  • 1 cup shredded Cheddar (or Colby Jack)

  • ½ cup grated Parmesan

  • ½ tsp garlic powder

  • ½ tsp onion powder

  • Salt & pepper, to taste

  • ½ cup Panko breadcrumbs

  • 2 tbsp melted butter (for topping)


👩‍🍳 Instructions

  1. Prep the zucchini

    • Grate or dice. Toss with ½ tsp salt and let sit for 10 minutes to draw out moisture. Squeeze dry with a towel or hands.

  2. Sauté aromatics

    • Preheat oven to 350°F (175°C); grease an 8Ă—8 or 9Ă—13 baking dish.

    • Melt 2 tbsp butter in a skillet; cook onion (and garlic, if using) until soft (about 3–4 min).

  3. Mix the casserole

    • In a bowl, whisk eggs with garlic powder, onion powder, salt, and pepper.

    • Add drained zucchini, sautĂ©ed onion, Cheddar, Parmesan, and stir to combine.

  4. Bake

    • Transfer mixture into the baking dish. Bake uncovered for 20–25 minutes until edges are bubbling.

  5. Add crisp topping

    • Toss breadcrumbs with melted butter. Sprinkle evenly over the casserole. Bake another 5–10 min until topping is golden brown.

  6. Rest & serve

    • Let cool 5–10 minutes before serving. Garnish with chopped fresh parsley or chives, if desired.


âś… Tips & Variations

  • Cheese swaps: Use Monterey Jack + Parmesan for a milder taste, or add Mozzarella for an even gooier texture.

  • Low‑carb option: Skip the Panko or substitute with crushed pork rinds.

  • Add-ins: Stir in crisp bacon, diced ham, or shredded chicken for a fuller main-course casserole.

  • Herb boost: Fresh basil or thyme adds fresh brightness.


🍽 Serving Suggestions

  • Great alongside grilled meats, roasted chicken, or as part of a brunch spread.

  • Pairs beautifully with a crisp green salad and crusty bread to soak up any cheesy goodness.


đź§© What to Prep Ahead
