Serves 6 hearty portions
Difficulty level
Easy – Perfect for beginner and intermediate home cooks alike
Ingredients
- 6 slices whole-grain bread, cubed (day-old or lightly toasted works best)
- 2 ripe avocados, peeled and mashed
- 4 large eggs, beaten
- 1 cup whole milk or unsweetened almond milk
- 1 cup shredded sharp cheddar cheese
- 1/2 cup cherry tomatoes, halved
- 1/4 cup chopped fresh cilantro or parsley
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 tablespoon olive oil
- 1 teaspoon smoked paprika
- Salt and black pepper, to taste
- Optional: pinch of red pepper flakes for heat
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch casserole dish.
- Prepare the bread: Cube the whole-grain bread into bite-sized pieces. For extra crunch,toast the cubes lightly in the oven for 5 minutes before assembling.
- Sauté the aromatics: In a skillet over medium heat, warm the olive oil. Add the diced onion and minced garlic, cooking until translucent and fragrant-about 4 minutes. Stir often to avoid burning.
- Mix the custard base: In a large bowl,whisk together eggs,milk,smoked paprika,salt,and pepper. Incorporate the mashed avocado gently to maintain some creamy texture.
- Combine all components: Fold the bread cubes, sautéed onion mixture, cherry tomatoes, and chopped herbs into the avocado-egg mixture. Stir gently to coat everything evenly.
- Transfer to casserole dish: Pour the mixture evenly into the prepared dish. Sprinkle shredded cheddar cheese over the top for a bubbly, golden crust.
- Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the top is set and lightly browned. A knife inserted in the centre should come out clean.
- Rest and serve: Let the casserole cool for 5 minutes before slicing. This resting step helps the casserole firm up for perfect portions.
Tips for Success
- Avocado Selection: Use ripe but firm avocados to ensure a creamy texture without over-mushiness.
- Customize the Bread: For gluten-free or grain-free alternatives, swap the bread cubes with seasoned cauliflower rice or cooked quinoa.
- Make Ahead: Prepare the mixture the night before and refrigerate, then bake fresh in the morning for an effortless breakfast.
- Cheese Variations: Try pepper jack for a spicy kick or feta for a tangy contrast.
- Keep Moisture Balanced: If you find the casserole too wet, reduce the milk quantity by 1/4 cup next time.
Serving Suggestions
Drizzle with a tangy chipotle aioli or a simple squeeze of fresh lime juice to enhance the avocado’s buttery notes. Garnish with microgreens, extra cilantro, or thinly sliced radishes for a pop of color and crunch. Pair with fresh fruit salad or a chilled green smoothie to round out your morning.
