How to Make Sweet Potato Breakfast Casserole Recipe

Step 1: Prep and Sauté the Vegetables

Start by heating the avocado or olive oil in a large skillet over medium heat. Toss in the diced sweet potato, red onion, and red bell pepper. Sprinkle with garlic powder, Italian seasoning, fennel, ground sage, salt, black pepper, and cayenne. Cooking these until the sweet potatoes are tender but still hold their shape, about 8-10 minutes, will release their natural sweetness and blend the spice medley beautifully. Stir often to avoid sticking and promote even cooking.

Step 2: Wilt the Spinach

Once the sweet potato and other veggies are nearly cooked, add the fresh spinach to the skillet. Stir it gently until it wilts, transforming from bright green leaves to a silky layer that locks in both freshness and vibrant color. This step ensures every forkful is packed with a balance of flavors and textures.

Step 3: Prepare the Egg Mixture

While the veggies are finishing up, crack the eggs into a large bowl. Whisk them thoroughly with a pinch of fine salt and pepper until the yolks and whites are fully combined and slightly frothy. This will ensure your casserole has a lovely, airy consistency once baked.

Step 4: Combine and Transfer to Baking Dish

Pour the sautéed vegetable mixture into the egg bowl and mix it gently but thoroughly. Pour the whole mixture into a greased casserole dish, spreading it evenly. This is where the magic begins as the eggs will set around the sweet potatoes and spinach, creating that irresistible breakfast centerpiece.

Step 5: Bake to Perfection

Place the dish in a preheated oven at 350°F (175°C) and bake for about 25-30 minutes. You’ll know it’s done when the top is golden and the eggs are set but still moist. Let it cool slightly before slicing, which helps everything hold together beautifully.

FAQs

Can I use regular potatoes instead of sweet potatoes?

While regular potatoes can work, sweet potatoes add a natural sweetness and creaminess that really defines this casserole’s flavor profile. Using regular potatoes may change the taste and texture slightly.

Is this recipe suitable for meal prep?

Absolutely! The Sweet Potato Breakfast Casserole Recipe reheats wonderfully, making it ideal for preparing ahead of busy mornings or feeding a family over several days.

Can I add cheese to this casserole?

You can! Adding cheese like feta, cheddar, or goat cheese will add a delightful creaminess and tang. Just sprinkle it over the casserole before baking or mix it into the egg mixture.

What can I substitute for spinach?

Kale, Swiss chard, or even arugula can all work as green substitutes if you want a variation. Just be sure to sauté them properly to soften before combining with the eggs.

Is it possible to make this recipe vegan?

To make a vegan version, swap the eggs with a chickpea flour batter or tofu scramble mix, and ensure the oil used is plant-based. Keep in mind, the texture will be different but still delicious!
