Ingredients

Scale
  • 4 cups whole grain bread, cubed
  • 6 large eggs
  • 2 cups milk
  • 1/4 tsp salt
  • 1/2 tsp freshly cracked black pepper
  • 1/2 tsp ground mustard powder
  • 1 tbsp fresh thyme leaves
  • 2 tsp olive oil
  • 1/2 yellow onion, thinly sliced
  • 1 (8 oz) container baby portabella mushrooms, sliced
  • 1 can artichoke heart quarters, drained
  • 3/4 cup freshly grated parmesan cheese

Instructions

  1. If cooking right away, heat oven to 350°F. Grease an 8x8" baking dish.
  2. Cut bread into 1/2-inch cubes.
  3. In a large bowl, whisk together eggs, milk, salt, pepper, and mustard powder. Add bread cubes and thyme. Stir and set aside.
  4. In a large nonstick skillet, heat olive oil over medium-low heat. Add mushrooms and onions and cook, stirring, until softened, about 10 minutes. Remove from heat.
  5. Add mushroom mixture, artichokes, and 1/2 cup of parmesan to bread mixture. Stir and pour into greased baking dish. Sprinkle with remaining 1/4 cup parmesan. At this point, you can cover and refrigerate overnight, or cook right away.
  6. Bake 50-60 minutes, uncovered, until edges are golden and eggs are set. If you're baking it from the refrigerator, you may need to add a few minutes
  7. Remove from oven and cool 5-10 minutes before serving.

Notes

  • Store leftovers covered in the refrigerator for up to 4 days.
  • This is a great use for day old bread. If your bread is  super fresh and soft, toast it in the oven for a few minutes. This will 'stale' it so that it doesn't get too mushy in the egg mixture.
  • Gruyere or mozzarella cheese would also be delicious in place of parmesan.
