A Family Favorite: Mushroom and Spinach Frittata Recipe Memory

There’s something about weekend mornings in my kitchen that just calls for a hot pan, whisked eggs, and a pile of vegetables. This Mushroom and Spinach Frittata has been a staple in my house since my early twenties. I used to make it for my mom on slow Sundays, her sipping coffee while I sautéed mushrooms in olive oil. It’s a memory I cherish every time I recreate this dish.

Back then, I didn’t know much about cooking. I’d just grab what was in the fridge—leftover spinach, some onions, a little cheese—and hope it turned out well. Over the years, I’ve perfected the balance of earthy mushrooms, tender zucchini, sweet onions, and creamy eggs. Add a little garlic and a pinch of red pepper flakes, and it becomes the kind of comfort food that’s healthy but never boring.

This Mushroom and Spinach Frittata is great for brunch, lunchboxes, or even light dinners. You can pair it with a fresh cucumber tomato salad or serve it alongside garlic butter baked salmon for a complete meal.

And hey, if you’ve tried my easy frittata recipe for summer brunch before, this one brings a new twist. It’s hearty enough to satisfy, but still light and veggie-forward—the perfect in-between.
