Notes

We tested this taco bake casserole with tomatoes added directly to the baking dish and found that baking closer to 35 minutes helps the eggs fully set. For best results, let the taco bake rest for at least 5 minutes before serving so it holds together better when sliced.

Tips for Best Results

• Bake closer to 35 minutes if the mixture looks wet
• Let it rest before cutting to help it set
• Broil for 1–2 minutes for a golden cheese top
• If not using a greased dish, loosen edges before serving

Variations & Substitutions

• Add tortillas: turn into a layered taco bake with tortillas
• Make it spicy: add jalapeños or chili flakes
• Dairy-free: use dairy-free cheese or skip cheese
• Lower sodium: use low-sodium taco seasoning
• Extra protein: add more beef or mix in ground turkey

Serving Suggestions
