My meat and potatoes husband extends his carnivore preferences to brunch, too. This cheesy Ham & Mushroom Strata hit the mark.

This breakfast casserole recipe is perfect for overnight guests, Mother’s Day or Easter brunch, or anytime you want to treat your family to a special breakfast!

Ham & Mushroom Strata

I’ve baked up iterations of this strata for years and years. This time, I swapped out my usual cheese for my favorite extra sharp cheddar. Smart move.  Plus I sliced up some challah instead of a sturdy sandwich bread. You know the drill. Just make it your own. The bread, the cheese, the inclusion of mushrooms are all up to you.

Bill’s mom tried to trick him into trying mushrooms by calling them fried marshmallows. Didn’t work. I just eat his share. This breakfast casserole is marvelous with ham, but you could certainly add Italian sausage or even bacon if you prefer.

How to Plan a Brunch

Start by collecting the best brunch recipes, from cocktails to cakes, quick bread, tarts, and quiche, so there is something for everyone! Brunch comes from combining the words “breakfast” and “lunch” and is generally served between 10 AM and 2 PM.

  • Start with what will be considered your brunch entree. It should include some protein source, whether ham, bacon, eggs, cheese, milk or cream. Breakfast casseroles, stratas, omelets, quiche, scrambled eggs, etc. are all terrific ideas.
  • Add some healthy fare, like a simple fresh fruit salad or fruit platter, crudite, smoked salmon platter for those watching their calories or carbs. A yogurt parfait layered with yogurt, fruit and granola is beautiful served in glass dishes.
  • Starches are important, too. Besides toast, bagels or English muffins, scones, muffins and pastries or coffeecakes, you can offer hash browns, biscuits, pancakes or waffles. Crepes and French toast are some of my favorites.
  • Keep your warm dishes warm and cold dishes cold by keeping them in the oven or fridge until just before serving. As always, don’t leave out food that can spoil for more than 2 hours at room temperature. This is the FDA’s recommendation to avoid food poisoning.
  • Make sure you have beverages for all ages. I like having a fruit juice, coffee, tea and even a breakfast cocktail, like these Grand Marnier Mimosas, if the brunch is a special occasion.
  • Set up a coffee and/or tea bar with cream, creamers, sugar and sugar substitutes, honey, lemons, cups, mugs, stirring spoons or sticks, and a spot to deposit used tea bags.
  • Know the needs of your guests. Whether it’s young children, vegans or those with gluten intolerance, adjust your menu accordingly.
  • Most of all, make it fun for all by keeping the conversation going. Ask questions, tell stories and make it a memorable occasion!
