Golden Onion Strata With Gruyere & Prosciutto

Recipe by Kater

I made this several years back as a side dish for Thanksgiving and it was a big hit. The recipe comes from Cooking Light's 2001 Annual Recipes. I think bacon could easily be substituted for the proscuitto too. Prep time does not reflect the time for sauteeing the onions and proscuitto or the chilling time.

Ingredients Nutrition


  1. Heat a large nonstick skillet over medium high heat.
  2. Add onion & proscuitto, and saute 5 minutes or until onion begins to brown.
  3. Add water; cover, reduce heat and simmer 30 minutes. Uncover and simmer 30 minutes or until liquid almost evaporates. Cool.
  4. Combine milk, mustard, pepper, and egg substitute in a large bowl and stir with a whisk until mixture is well blended.
  5. Stir in onion mixture. Add bread, tossing gently to coat.
  6. Arrange half of bread mixture in a single layer in an 11x7" baking dish. Sprinkle with 1/2 cup cheese and top with remaining bread mixture.
  7. Cover strata and chill for 8 hours or overnight.
  8. Preheat oven to 350 degrees.
  9. Uncover strata and bake at 350 for 25 minutes. Sprinkle with 1/2 cup cheese; bake an additional 20 minutes or until set.
