Caramelized Onion, Bacon and Kale Strata

When I host my friends, this comforting strata is my go-to recipe. I created it in winter to help me get through the snowstorms and shoveling. —Linda Dalton, Stoughton, Massachusetts

    6 servings


  • 6 bacon strips, chopped

    Since I couldn't find gorgonzola cheese, I used goat milk cheese. I think that is why my dish wasn't very good. The bread was soggy.

    Made this Strata for Christmas brunch. What a Hit! I never make the same breakfast each year but the company said this is a keeper and they expect it again.

    Oh, this is good! Nice and hearty on a cold evening. We used the cream instead of the 2% milk. I was skeptical about the gorgonzola cheese, but it tasted great. Other cheeses with deep flavor can be substituted and it is still very satisfying.

    My husband and I made this with homemade bread for our mother's day brunch this year and it was a hit! We did use kale. We also used feta cheese and mozzarella cheese instead of the suggested cheeses since that is what we had on hand. This recipe had a ton of depth and flavor.
