Pro Tips for Perfect Results

  • No watery squash? Drain excess liquid after cooking—use a slotted spoon to transfer to bowl.
  • Crispier top? Switch oven to broil for 2–3 minutes at the end—watch closely!
  • Cheese variations: Try Monterey Jack, pepper jack, or mozzarella for different flavors.
  • Bulk up the veggies: Add 1 cup diced zucchini or bell pepper for extra color and nutrition.

Variations to Suit Every Table

  • 🥓 Bacon‑Loaded: Stir in 1 cup cooked, crumbled bacon before baking.
  • 🌶️ Spicy Kick: Add chopped jalapeños or a pinch of cayenne.
  • 🥦 Veggie Packed: Mix in cooked small broccoli florets for a veggie boost.
  • 🧀 Deluxe Cheese: Use half cream cheese in the filling for extra richness.

Make‑Ahead & Storage Tips

  • Prep Ahead: Fully assemble to the breadcrumb stage, cover, and refrigerate up to 24 hours before baking.
  • Leftovers: Store in an airtight container in the fridge up to 3–4 days.
  • Reheat: Place in 350°F oven for 15–20 minutes until warmed through. A quick broil refreshes the crispy top.
