Onion, Bacon, and Swiss Cheese Strata Recipe

Inspired by spending a few too many nights in Munich's beer halls, this brunch casserole is perfect for those of us who like to plan ahead for the morning after a long night at the bar. It's a hearty strata inspired by dish commonly found in beer halls throughout Germany called kaese spaetzle. Traditionally, kaese spaetzle is a dish of delicate spaetzle (small dumplings) tossed with onions and emmantaler cheese, and baked until bubbling. This strata removes the spaetzle and replaces it with baguette, and adds a few bits of bacon.

If you have truly outdone yourself at the bar, you may consider reaching for a cold glass of beer to go along with this substantial casserole. A glass of beer, a heap of cheese- and bacon-studded casserole, and a big green salad later, you'll feel ready once again to tackle the world in no time flat.

  • Yield:Serves 4 (or 6 as a side)
  • Active time: 25 minutes
