Ingredients

• 1 large head cauliflower
• 4 slices rye bread
• 3 large eggs
• 1.5 cups milk
• 2 cups cheddar cheese, shredded
• 1 medium yellow onion, diced
• 2 tablespoons butter
• 2 cloves garlic, minced
• 1 tablespoon dijon mustard
• 2 tablespoons fresh parsley, chopped
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 tablespoon olive oil

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with butter or olive oil and set aside.

Step 2

Cut the cauliflower into small florets. Steam the florets in a pot with a steamer basket for about 5-7 minutes, or until tender but not mushy. Drain and set aside.

Step 3

In a medium skillet over medium heat, warm the olive oil. Add the diced onion and cook for 3-4 minutes until translucent. Stir in the minced garlic and cook for another 1 minute. Remove from heat.

Step 4

Tear the rye bread slices into small pieces and place them in a large mixing bowl.

Step 5

In a separate bowl, whisk together the eggs, milk, dijon mustard, salt, and black pepper. Pour this egg mixture over the torn rye bread and toss until the bread soaks up the liquid.

Step 6

Add the steamed cauliflower, cooked onion and garlic mixture, shredded cheddar cheese (reserve 1/2 cup for topping), and fresh parsley to the bowl with the bread mixture. Gently fold until everything is evenly combined.

Step 7

Transfer the mixture to the prepared casserole dish, spreading it out evenly. Sprinkle the reserved 1/2 cup of cheddar cheese over the top.

Step 8

Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the casserole is set in the center.

Step 9

Remove the casserole from the oven and let it cool for 5 minutes before serving. Sprinkle additional fresh parsley on top if desired.

Step 10

Serve warm and enjoy!
