Ingredients You'll Need

Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.

  • 2 lbs Boneless, skinless morsels (cut into 1-inch pieces)
  • 2 tablespoons Olive oil
  • 1 medium Yellow onion (diced)
  • 2 stalks Celery (diced)
  • 2 cloves Garlic (minced)
  • 1/4 cup All-purpose flour
  • 2 cups Chicken broth (low sodium)
  • 1 cup Heavy cream
  • 1 cup Frozen peas
  • 1 cup Frozen carrots
  • 1/2 teaspoon Salt (or to taste)
  • 1/4 teaspoon Black pepper (or to taste)

Step-by-Step Instructions

  1. 1

    Preheat your oven to 375°F (190°C). This ensures the casserole cooks evenly and the top browns beautifully. Prepare a 9x13 inch baking dish by lightly greasing it with cooking spray or olive oil.

    ~5 min

  2. 2

    Heat olive oil in a large skillet over medium-high heat. Add the morsels and cook until browned on all sides, about 5-7 minutes. Don't overcrowd the pan; work in batches if necessary to ensure proper browning which adds depth of flavor.

    ~7 min

  3. 3

    Remove the morsels from the skillet and set aside. Add the diced onion and celery to the same skillet and cook until softened, about 5 minutes. The vegetables should be translucent and slightly fragrant.

    ~5 min

  4. 4

    Add the minced garlic to the skillet and cook for another minute until fragrant. Be careful not to burn the garlic, as it can become bitter. The aroma should be savory and inviting.

    ~1 min

  5. 5

    Sprinkle the flour over the vegetables and cook for 1 minute, stirring constantly. This creates a roux that will thicken the sauce. Make sure the flour is fully incorporated and there are no lumps.

    ~1 min

  6. 6

    Gradually whisk in the chicken broth, scraping the bottom of the skillet to loosen any browned bits. This adds flavor and prevents the sauce from sticking. Continue whisking until the sauce is smooth and thickened.

    ~3 min

  7. 7

    Stir in the heavy cream, salt, and pepper. Bring the sauce to a simmer, then reduce heat and cook for 5 minutes, or until slightly thickened. The sauce should coat the back of a spoon.

    ~5 min

  8. 8

    Add the browned morsels, frozen peas, and frozen carrots to the skillet. Stir to combine and ensure everything is coated in the sauce. The frozen vegetables will thaw and cook in the oven.

    ~2 min

  9. 9

    Pour the mixture into the prepared baking dish. Spread evenly to ensure uniform cooking. The casserole should be about 1-inch deep in the dish.

    ~1 min

  10. 10

    Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and golden brown on top. The sauce should be thickened and the vegetables tender. A slight browning on top indicates caramelization and added flavor.

    ~30 min

  11. 11

    Let the casserole cool for a few minutes before serving. This allows the sauce to thicken slightly and prevents burning your mouth. Garnish with fresh parsley, if desired.

    ~5 min

How Do I Know It's Ready?

The casserole is done when the sauce is bubbly and thickened, and the vegetables are tender. The top should be lightly browned. An internal temperature of 165°F (74°C) ensures the morsels are cooked through.
