How to Make Garlic Roasted Broccoli and Ground Beef

Preheat the oven. Begin by setting your oven to 400°F (200°C). This ensures the casserole bakes evenly, creating that delicious roasted flavor.
Sauté the onion. In a skillet, heat 1 tablespoon of olive oil over medium heat. Add the chopped onion, and sauté for about 5 minutes until it’s softened and translucent.
Cook the ground beef. Add 1 pound of lean ground beef to the skillet with the onions. Cook until the beef is browned, stirring occasionally; season it with salt and pepper, then remove from heat.
Prepare the broccoli. In a baking dish, layer 5 cups of broccoli florets. Add the minced garlic, drizzle with 2 tablespoons of olive oil, and season generously with salt and pepper. Bake for 20 minutes, stirring halfway to ensure even roasting.
Make the creamy sauce. In a bowl, combine 2 ½ tablespoons of almond milk and ⅓ cup of mayonnaise. Whisk in 1 teaspoon of arrowroot flour and 1 tablespoon of nutritional yeast until smooth and creamy.
Combine the ingredients. Once the broccoli is tender, mix in the ground beef and onion mixture. Then drizzle the creamy sauce over the top and gently combine everything. Bake for an additional 15-20 minutes, or until you see a light golden brown on top.
Serve hot. Once out of the oven, serve the casserole immediately while it’s warm and comforting—enjoy those delicious aromas!

Optional: Garnish with fresh chopped parsley for a vibrant touch.
