Ingredients

Scale

Vegetables

  • 30 oz. bag frozen California vegetables (thawed)

Soup & Dairy

  • 21 oz condensed cream of chicken soup (2 cans, 10.5 oz each)
  • 1 cup sour cream
  • 1/2 cup chicken broth
  • 2 cups Monterey Jack cheese (shredded)

Seasonings & Toppings

  • 1 tablespoon garlic (minced)
  • 2 teaspoons salt
  • 2 teaspoons black pepper
  • 2 teaspoons dried oregano
  • 6 oz can French fried onions


Instructions

  1. Preheat Oven: Preheat your oven to 350 degrees F. Spray a casserole dish with non-stick cooking spray and set it aside to prepare your mixture.
  2. Prepare Sauce: In a large mixing bowl, combine the condensed cream of chicken soup, chicken broth, sour cream, salt, pepper, garlic, and dried oregano. Mix thoroughly to create a smooth, flavorful base.
  3. Add Vegetables and Cheese: Stir in the thawed California vegetables and 1 cup of the shredded Monterey Jack cheese into the sauce mixture until well combined.
  4. Assemble Casserole: Pour the vegetable mixture evenly into your prepared casserole dish, spreading it out smoothly.
  5. Add Toppings: Sprinkle the remaining shredded Monterey Jack cheese over the top of the casserole, then evenly distribute the French fried onions as a crispy topping.
  6. Bake: Place the casserole dish in the preheated oven. Bake uncovered for 30 minutes, then cover it with foil and bake for an additional 10 minutes to meld flavors and soften the vegetables thoroughly.
  7. Cool and Serve: Remove the casserole from the oven and let it cool for about 10 minutes before serving to allow it to set and become easier to serve.

Notes

  • Make sure the frozen vegetables are fully thawed before mixing to avoid excess water in the casserole.
  • You can substitute the cream of chicken soup with a cream of mushroom soup for a different flavor profile.
  • Feel free to add other seasonings such as thyme or rosemary for additional flavor.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven to retain crispiness.
  • Use sharp cheddar or a cheese blend in place of Monterey Jack if preferred.
