Bacon and Onion Stuffed Mushrooms

Published on March 23, 2022 by Raveaboutfood

Bacon and Onion Stuffed Mushrooms are a great appetizer to serve before a steak dinner or a perfect side dish to a big plate of hot pasta. I also make them each year at Thanksgiving. My father-in-law really looks forward to eating these at the holidays. The whole family munches on stuffed mushrooms before we sit down to a traditional turkey dinner.

Mushrooms are earthy and meaty. They can be a side dish or a great lead-in to your meal. That is the case with this recipe, serve them as a tasty side dish to beef or chicken—or as a hearty appetizer. The bacon, onion and garlic combination makes these stuffed mushrooms shine.
