This bacon mushroom spinach quiche is a delicious make-ahead brunch or breakfast recipe!

Brunch is my favorite meal of the day to celebrate with friends and family. And, it's not brunch without bacon. Am I right? (NOD here. Thank you.)
For Mother's Day this year, hubby was out of town and I hosted brunch at our house for my parents and my brother and his family. Since I was flying solo with our two kids and a mountain of work that weekend, I needed quick, easy, make-ahead brunch dishes.
My go-to brunch recipe tends to be these Cheesy Spinach Mini-Frittatas. This salmon quiche is also lovely to make for brunch. But this bacon mushroom spinach quiche recipe is also a winner. It's satisfying and oh so delicious!
❤️ Why you'll love this quiche recipe

I love quiche because:
- you can enjoy it for breakfast, brunch, lunch, and dinner
- you can put almost any ingredients into it
- unless you go too heavy on an ingredient or two, you can usually just eyeball measurements and the dish still turns out a-okay, and
- you can make it the night before and just reheat before company comes over.
One of my favorite quiches is made with bacon, mushrooms, spinach, and cheddar cheese. Plus extra bacon. And extra cheese, if you've got it.
Tips & substitutions for bacon mushroom spinach quiche

If you're in a pinch, use a pre-made pie crust to help save time. But the BEST crust is this easy food processor pie dough recipe. It's SO good!
You can also use almost any cheese that you like. I really like the flavor that Sharp Cheddar Cheese brings to quiche. But you can also use Gruyere, Mild Cheddar, White Cheddar, or even a combo of Asiago, Parmesan, and Cheddar cheese.
Since becoming dairy-free, I've been making this quiche with my favorite dairy-free vegan cheeses.
If you want, you can substitute out mushrooms for other spring vegetables like asparagus or broccoli.
You can also use ham instead of bacon if you wish.

- ¾ cup of shredded sharp cheddar cheese or mix of your favorite cheeses

- Add chopped spinach to the pan and cook for another 2 minutes, until the spinach is slightly wilted (but not wilted!).
- Remove from heat and set aside.

I made this with leftover collard greens from Thanksgiving. All I had to do was cook the bacon and mushrooms and add to the eggs. Fabulous!
Marlynn Jayme Schotland says
So glad you loved it, Jennifer! Leftover collard greens sounds like a fantastic addition :)
Cynthia says
I added sage, garlic powder, and garlic powder. Then I put aluminum foil around the crust to keep it from getting too brown after the blind bake. Still runny inside after cooked acc. to instructions, however, it was a beautiful brown. Therefore, I covered the whole top in aluminum foil, llowered heat to 350, and cooked 15 min. more.. It fluffed up beautifully!!!
Marlynn Jayme Schotland says
Glad it turned out well! Thanks for sharing your experience making this quiche, Cynthia! I've never had it turn out too soft or runny at the full bake time, but it helps others know what you did in case that happens to them, too :) Appreciate it!
elaine martell says
I was surprised the recipe did not say to drain the bacon grease. Six slices renders a lot of fat that I would think no one would want in the quiche. I drained all but what I needed to sauté the mushrooms.
Ashley says
I also drained the fat, but the final product was delicious!
Marlynn Jayme Schotland says
Glad you liked it, Ashley! :)
Ed says
This was delicious! The only thing I did differently was to add extra spinach.
Marlynn Jayme Schotland says
Glad to hear you enjoyed it, Ed! :)
Marlynn Jayme Schotland says
It really is great for using up leftovers of all kinds!
Pech says
Haha, so true that quiche is how I tend to use up leftover eggs... and anything else leftover at the time too...
Aubrie LeGault says
Awesome, I love quiches. Thanks.
Sarah says
I love brunch too! And you had me at bacon and mushrooms...
Catherine says
I really like the idea of quiche for all the reasons you mentioned, but when I make it, it usually turns out too jiggly and custard-like. Any recs to get it more scrambled egg-y or firmer?
Marlynn Jayme Schotland says
Hmm...it could be a couple of things. Sometimes if you don't beat the eggs enough or put too many eggs in relation to the other filling items, it can be runny. I've also found that it definitely needs some sort of thickener like the cheese to help bind it together more, so you could try adding more cheese. Hope that helps!
Kira says
Looks great! I have never actually made a quiche before.
Marlynn Jayme Schotland says
Thanks, Kira! It's honestly super easy to make (and yummy!). Give it a try!
Jada says
This looks so yummy! I'm trying to convince someone to make this for me!
Marlynn Jayme Schotland says
Thanks, Jada! I hope you are successful in your efforts to have someone make this for you ;)
Melinda says
My husband loves quiche, so I may make this for him sometime!
Marlynn Jayme Schotland says
Great! Let me know how it goes if you ever do make it, Melinda. I'd love to hear! Just remember: it's fairly forgiving as long as you keep in mind the ratio of ingredients.
