👩🍳 Directions
Step 1 – Preheat the Oven
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or nonstick spray.
Step 2 – Sauté the Onion
In a skillet over medium heat, melt 1 tablespoon of butter. Add the finely diced onion and cook for 3–4 minutes until soft and fragrant. This step builds the flavor base of your casserole.
Step 3 – Prepare the Creamy Base
In a large mixing bowl, combine cream of mushroom soup, milk, sour cream, whisked eggs, half of the shredded cheddar cheese, and the cooked onion. Whisk until smooth and creamy.
Step 4 – Add the Vegetables and Rice
Stir in the frozen broccoli florets, mixed vegetables, and cooked rice. Mix gently to coat everything evenly with the creamy sauce.
Step 5 – Season Well
Add garlic salt, salt, mustard powder, Italian seasoning, and black pepper. Stir well to combine. Taste and adjust seasoning as needed.
Step 6 – Transfer to Baking Dish
Pour the mixture into the prepared baking dish and spread evenly. Sprinkle the remaining cheddar cheese over the top.
Step 7 – Prepare the Cracker Topping
In a small bowl, mix the crushed Ritz crackers with melted butter. Stir until the crumbs are evenly coated.
Step 8 – Add the Topping
Sprinkle the buttery cracker mixture over the casserole, covering the surface evenly for that golden, crispy finish.
Step 9 – Bake to Perfection
Bake uncovered for 35–40 minutes, until the top is golden brown and the casserole is bubbly around the edges.
Step 10 – Cool Slightly & Serve
Let it cool for 5–10 minutes before serving. The flavors settle beautifully, and the texture becomes perfectly creamy yet firm.
