For the Cheese Sauce

We carefully select these ingredients to balance savory meatiness with creamy cheese and a crispy topping. This ensures our Holy Moly Casserole bursts with flavor and satisfies every bite.
Equipment Needed
To prepare the Holy Moly Casserole with ease and precision, having the right equipment is essential. Below is a detailed list of the tools we’ll use to execute each step smoothly and achieve that perfect savory result.
| Equipment | Purpose |
|---|---|
| Large Skillet or Frying Pan | To brown the ground beef and sauté onions and garlic |
| Medium Saucepan | To prepare the creamy cheese sauce |
| Mixing Spoon or Spatula | To stir ingredients during cooking |
| 9×13 Inch Casserole Dish | For layering and baking the casserole |
| Measuring Cups and Spoons | To ensure precise ingredient measurements |
| Cheese Grater | To shred cheddar and mozzarella cheeses |

We recommend using a non-stick skillet for easier cooking and quick cleanup. For the casserole dish, a glass or ceramic option holds heat evenly, guaranteeing thorough baking of all layers.
Prep Work
To ensure our Holy Moly Casserole Recipe comes together smoothly, preparation is key. Let’s get everything ready step-by-step for a seamless cooking experience.
Preparing the Ingredients
Before we start cooking, follow these preparation steps for each ingredient:
- Ground beef: Measure out 1 pound. Make sure to pat it dry if excessively wet for better browning.
- Onion: Peel and finely dice 1 medium onion to release its natural sweetness during sautéing.
- Garlic: Mince 2 cloves to evenly distribute sharp, aromatic flavor throughout the casserole.
- Mixed vegetables: Use 1 cup of frozen mixed vegetables. Thaw slightly or rinse under cold water to reduce excess ice.
- Diced tomatoes: Drain 1 can (14.5 oz) briefly to control moisture but retain juiciness.
- Butter, flour, milk, and cheddar cheese: Measure precisely for the creamy cheese sauce.
- Mozzarella cheese and crushed crackers or breadcrumbs: Set aside for topping the casserole.
- Fresh parsley: Chop roughly 1 tablespoon for garnish and freshness.
| Ingredient | Prep Details | Quantity |
|---|---|---|
| Ground beef | Pat dry | 1 lb |
| Onion | Peel and finely dice | 1 medium |
| Garlic | Mince | 2 cloves |
| Mixed vegetables | Thawed or rinsed | 1 cup |
| Diced tomatoes | Drain briefly | 1 can (14.5 oz) |
| Butter | Measured | 3 tbsp |
| Flour | Measured | 3 tbsp |
| Milk | Measured | 2 cups |
| Cheddar cheese | Grated | 1 ½ cups |
| Mozzarella cheese | Grated | 1 cup |
| Crushed crackers | Ready for topping | ½ cup |
| Fresh parsley | Roughly chopped | 1 tbsp |
Preheating the Oven
Preheating the oven is essential for even baking and a perfectly cooked casserole. We recommend:
- Setting the oven to 350°F (175°C).
- Allow enough time (at least 10 minutes) for the oven to reach the temperature before placing the casserole inside.
- This step ensures the casserole cooks through evenly and develops a golden brown, bubbling top.
Tip: While the oven preheats, you can complete cooking your beef and vegetables to optimize your workflow.
Directions
Follow these step-by-step instructions to create the Holy Moly Casserole that bursts with flavor and comfort in every bite.
Making the Casserole Base
- Heat a large non-stick skillet over medium-high heat.
- Add 1 pound (450 g) of ground beef. Brown the beef, breaking it up with a spatula. Cook until no pink remains, about 5-7 minutes.
- Drain excess fat from the skillet to keep the casserole from becoming greasy.
- Add 1 medium onion, finely diced, and 2 cloves garlic, minced to the beef. Sauté for 3-4 minutes until the onions soften and become translucent.
- Stir in 1 cup (150 g) of thawed mixed vegetables and 1 can (14.5 oz / 411 g) of drained diced tomatoes. Simmer for 5 minutes to blend flavors.
- Season with salt and pepper to taste. Remove from heat.
Preparing the Cheese Sauce
- In a medium saucepan, melt 3 tablespoons (43 g) butter over medium heat.
- Whisk in 3 tablespoons (24 g) all-purpose flour gradually to form a smooth roux. Cook for 1-2 minutes without browning.
- Slowly whisk in 2 cups (480 ml) milk to avoid lumps. Continue whisking until the mixture thickens and bubbles, about 5 minutes.
- Remove from heat and stir in 2 cups (226 g) shredded cheddar cheese until melted and creamy.
- Add a pinch of salt and a dash of black pepper. Keep warm.
Assembling the Casserole
- Preheat the oven to 350°F (175°C) if not already done.
- Spread the beef and vegetable mixture evenly in a 9×13 inch (23×33 cm) casserole dish.
- Pour the warm cheese sauce evenly over the meat layer, gently smoothing the top.
- Sprinkle with 1 cup (113 g) shredded mozzarella cheese for extra gooeyness.
- Top with 1 cup (60 g) crushed crackers or breadcrumbs to add crispy texture.
- Optionally garnish the top with 2 tablespoons chopped fresh parsley for color and freshness.
Baking
| Step | Instruction | Time | Temperature |
|---|---|---|---|
| Bake casserole | Place dish in preheated oven | 25-30 minutes | 350°F (175°C) |
| Rest after bake | Remove casserole and let cool slightly | 5-10 minutes | Room temperature |
- Bake the casserole uncovered on the middle rack for 25-30 minutes until bubbly and golden on top.
- Remove from oven and let rest for 5-10 minutes before serving to allow layers to set.
- Scoop generous portions and enjoy the Holy Moly Casserole’s rich, cheesy goodness and savory layers in every bite.
