Make-Ahead Mushroom and Feta Egg Bites

Savory baked egg cups loaded with sautéed mushrooms, bell peppers, feta, and parmesan cheese. These protein-rich bites work for meal prep, brunch, or quick breakfasts. The combination of earthy mushrooms and tangy cheeses creates depth, while the custardy egg base holds everything together. Make a batch on Sunday and portion throughout the week. This version uses two cheeses for complexity and fresh herbs for brightness, distinguishing it from simpler versions.

Tips
Fill muffin cups only two-thirds full so egg rises slightly without overflowing. The bites will puff during baking and settle as they cool.
For easier removal, use silicone muffin liners or ensure pan is well oiled. Bites release cleanly from hot pans; let them cool 2 minutes before turning out if using metal.
Good to Know
Keep in an airtight container in the refrigerator for up to 5 days. Cool completely before storing.
Prepare through step 9 the night before. Cover and refrigerate mushroom mixture and egg mixture separately. Combine and bake the next morning.
Serve warm from the oven with hot sauce, salsa, or sour cream on the side. Cold bites work well as grab-and-go snacks.
Common Mistakes
Overfill muffin cups to avoid eggs spilling out during baking
Undercook the mushrooms to avoid a rubbery, dry texture

FAQ
Can I freeze these egg bites?
Yes. Cool completely, arrange on a baking sheet, freeze until solid (about 2 hours), then transfer to a freezer bag for up to 2 months. Reheat in a 350F oven for 8-10 minutes from frozen.
What if I don't have a muffin pan?
Use a silicone egg bite mold or ramekins instead. Adjust baking time slightly depending on vessel size; start checking at 15 minutes.
How long do these keep at room temperature?
Up to 2 hours. For longer periods or meal prep, refrigerate and reheat before serving to avoid food safety issues.
