On the stove

1. Preheat the Oven: Set your oven to 200°C | 375°F and lightly spray a 9×13-inch baking dish with cooking oil spray. This helps the casserole bake evenly and release easily after cooking.

1. Cook the Sweet Potatoes: Heat a tablespoon of olive oil in a large skillet over medium heat. Add the diced sweet potatoes and fry for about 2 minutes to crisp the edges.

1. Steam and Soften: Cover the pan with a lid and let the sweet potatoes cook for around 10 minutes, stirring occasionally, until they're fork-tender.

1. Brown the Sausage: In the same skillet, cook the sausage meat, breaking it apart with a wooden spoon. Fry until browned and crisp for maximum flavor.

1. Sauté the Vegetables: Add the onion and garlic to the sausage and cook until fragrant and translucent. Toss in the bell peppers and mushrooms, then cook for another 3 minutes before adding the spinach to wilt.

1. Combine Everything: Season the sausage and veggie mixture with salt and pepper. Transfer it to the baking dish with the sweet potatoes, add the halved tomatoes, and mix everything together gently.

1. Whisk the Eggs: In a large bowl, whisk the eggs with milk and half of the shredded cheese. Pour this mixture over the casserole and top with the remaining cheese.

1. Bake: Bake uncovered for about 45 minutes, or until the top is golden. Let it cool slightly, slice into portions, and serve warm for the good meal any time of day.

This Sweet Potato Hash Brown Casserole pairs beautifully with cozy comfort foods or something a little fresh and indulgent on the side. For breakfast or brunch, serve it alongside Strawberries and Cream Stuffed French Toast for a mix of savory and sweet that feels like the weekend in every bite. If you're making it for dinner, try it with Creamy Chicken and Mushroomwhere the rich, buttery sauce complements the hearty sweetness of the potatoes.

Kitchen tip

• We like using pre-cut or frozen sweet potatoes on busy mornings. They roast up just as crisp and save us all that peeling and dicing.
• Don't skip browning the sausage; it's what gives this casserole its rich, savory flavor that ties everything together.
• Let it rest for about 10 minutes before cutting in. Trust us, it holds together better and the layers settle beautifully.
• Feel free to switch things up with bacon, ham, or even plant-based sausage if that's more your style.

Recipe FAQ's

You can, but the flavor will be different. Sweet potatoes add a natural sweetness and beautiful color that make this casserole special.

We love using mild Italian sausage or chicken sausage for a balanced flavor, but spicy sausage works if you like a little kick in the morning.

It's ready when the top is golden, the edges are slightly crisp, and the center is set. A quick test with a knife should come out clean.
