- Sauté the aromatics: Heat olive oil in a skillet over medium heat. Add the minced garlic and diced red bell pepper, sautéing until fragrant and softened (about 3-4 minutes). Stir frequently to avoid burning.
- Add spinach and green onions: Toss in the chopped spinach and green onions.cook for an additional 2 minutes until the spinach wilts but retains its bright green color.

- Combine: Gently fold the sautéed vegetables, crumbled bacon, shredded cheddar, and Parmesan cheeses into the egg mixture. Ensure the ingredients are evenly distributed without overmixing.
- Transfer to baking dish: Lightly grease an 8×8-inch casserole dish with a non-stick spray or butter. Pour the mixture evenly into the dish.
- Bake uncovered: Place the casserole in the center rack of the oven.Bake for 35-40 minutes until the top is golden brown and a knife inserted in the center comes out clean.
- Rest before serving: Allow the casserole to cool for 5 minutes to set, which helps with cleaner slices and enhanced flavors.
Chef’s Notes

- Meat variations: Replace bacon with cooked sausage or diced ham to change up protein sources.
- Dairy alternatives: Use full-fat mozzarella or Gruyère cheese to vary flavor profiles.
- Make ahead: Assemble the casserole the night before and refrigerate, than bake fresh in the morning for convenience.
- Storing tips: Keep leftovers in an airtight container, refrigerate for up to 4 days, or freeze in portions for up to 2 months.
