Chicken Casserole Recipe:

Galina (my sister’s mama-in-law) is an amazing cook and this is her chicken and mushroom casserole and it is always a hit at parties and church potlucks. We make this often.

The chicken is incredibly tender – you will savor every morsel! I’ve seen sorta-somewhat similar recipes online referred to as Chicken Gloria, but I love that this one uses such simple, basic and non-canned ingredients! This chicken and mushroom casserole also re-heats really well (if you are lucky enough to have leftovers). You will likely add this recipe to your list of favorites.

Ingredients for Chicken Casserole :

The ingredients for this recipe are surprisingly simple but they just work [see full printable ingredient list below]:

  • Chicken breast (or chicken tenders)
  • Chicken broth
  • Half and Half*
  • All-purpose flour (or use a GF substitute)
  • Mushrooms
  • Onion – it disappears into the sauce
  • Garlic – don’t skip it
  • Lemon juice – fresh is best

*What Is Half and Half? If you aren’t able to find “half and half” at your grocery store, you can substitute with equal parts of milk and heavy cream.

Can I Substitute the Mushrooms?

You can replace white mushrooms with portabello mushrooms. If you don’t like mushrooms, you can substitute with different vegetables, just pick sturdy veggies (avoid zucchini which turns mushy). Here are some great options to replace mushrooms:

  • Frozen peas
  • Asparagus
  • Caramelized onions
  • Artichoke hearts (well-drained)

How to Make the Best Chicken Casserole:

1.  Season chicken with salt and pepper and dredge both sides in flour. Heat 3 Tbsp oil in a large skillet over medium/high heat. Once oil is hot, add chicken and saute until golden and transfer to a 13×9 casserole baking dish.

Cooks Tip: Work in batches if needed so you don’t crowd your pan. Don’t worry about cooking the chicken through; it still needs to go in the oven.

What To Serve with this Chicken Bake:

This chicken bakes in gravy so it is perfect served over creamy mashed potatoes or over egg noodles, the same way we serve Beef Stroganoff. We love pairing it with Baked Asparagus or a Cucumber Tomato Salad on the side.

Can Chicken Casserole Be Frozen?

Yes! You can freeze leftover chicken casserole. One of my readers shared her method: “It works! I took the pan out of the freezer, left it in the fridge most of the day and reheated it in a 350* oven for about 40 minutes.”
