Ingredients, Substitutions & Foolproof Tips
- 2 medium yellow squash: Base of the casserole, providing vitamins and minerals.
- 1 medium onion: Adds sweetness and depth of flavor.
- 1 cup shredded cheddar cheese: For creaminess and richness; can substitute with Monterey Jack for a milder taste.
- 1 cup milk: Binds the ingredients together; can use almond milk for lactose-free options.
- 2 large eggs: Helps set the casserole; can replace with a flaxseed meal for a vegan option.
- 1 cup breadcrumbs: Adds texture; panko works well for extra crunch.
- 2 tablespoons olive oil: For sautéing; coconut oil can be a healthier alternative.
- Salt and pepper to taste: Enhances overall flavor.
Step-by-Step Directions
- Preheat the oven: Start off by preheating your oven to 350°F (175°C). This ensures the casserole bakes evenly, giving you that perfect, golden finish.
- Slice the vegetables: Slice the 2 medium yellow squash and 1 medium onion. The thinner the slices, the quicker they’ll sauté.
- Sauté the squash and onion: In a skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced squash and onion, and sauté until tender—about 5-7 minutes. You want them softened but not mushy.
- Mix the egg and milk: In a mixing bowl, combine 1 cup of milk and 2 large eggs. Whisk together until well blended and frothy.
- Combine sautéed veggies: Stir in the sautéed squash and onion into the milk and egg mixture. This integrates those delicious flavors well.
- Add breadcrumbs and seasoning: Mix in the 1 cup of breadcrumbs, salt, and pepper. You’re looking for a well-combined mixture that holds its form slightly.
- Prepare for baking: Pour the mixture into a greased baking dish, spreading it out evenly. Top it off with the remaining 1 cup of cheddar cheese.
- Bake it: Put the dish in the oven and bake for 30-35 minutes, or until it’s golden brown and set. The delightful aroma will fill your home as it cooks!
Common Mistakes to Avoid & Pro Tips
- Mistake: Not sautéing the squash and onion long enough.
- Fix: Ensure they are tender before combining—this enhances the texture of your casserole.
- Mistake: Overbaking the casserole.
- Fix: Monitor closely toward the end of baking—look for a golden crust but a soft center.

- Pro Tip: Let the dish sit for a few minutes after baking to firm up; this makes serving much easier!
