Sweet Potato Casserole with Spinach and Cheese – A Must-Try Recipe!

### Instructions:

#### 1. **Prepare the Sweet Potatoes:**
Start by peeling and cubing the sweet potatoes into bite-sized pieces. Bring a large pot of salted water to a boil and add the sweet potatoes. Cook them for about 10-12 minutes, or until they are tender when pierced with a fork. Drain and set aside.

#### 2. **Sauté the Onion and Garlic:**
While the sweet potatoes are cooking, heat the olive oil in a large skillet over medium heat. Add the diced onion and sauté for 4-5 minutes, or until the onion becomes soft and translucent. Add the minced garlic and cook for an additional 1-2 minutes until fragrant.

#### 3. **Wilt the Spinach:**
Add the chopped spinach to the skillet with the onions and garlic. Cook for about 3-4 minutes, or until the spinach has wilted down. Stir occasionally to ensure the spinach cooks evenly. Once cooked, remove from heat and set aside.

#### 4. **Mash the Sweet Potatoes:**
Once the sweet potatoes are drained, transfer them to a large mixing bowl. Use a potato masher or a hand mixer to mash the sweet potatoes until smooth. You can leave them a little chunky if you prefer more texture.

#### 5. **Mix the Casserole Filling:**
To the mashed sweet potatoes, add the sour cream (or Greek yogurt), milk, salt, pepper, and nutmeg. Stir until well combined. Then, fold in the sautéed spinach and onion mixture. Add the shredded cheese and mix again until everything is evenly distributed.

#### 6. **Assemble the Casserole:**
Transfer the sweet potato mixture into a greased 9×13-inch baking dish or casserole dish. Spread the mixture evenly and top with a generous sprinkle of Parmesan cheese.

#### 7. **Bake the Casserole:**
Preheat your oven to **375°F (190°C)**. Place the casserole in the oven and bake for 20-25 minutes, or until the top is golden and the cheese has melted into a bubbly, creamy layer.

#### 8. **Serve and Enjoy:**
Once baked, remove the casserole from the oven and let it cool for a few minutes before serving. Garnish with fresh herbs like parsley or thyme for an added touch of freshness and color. This casserole pairs wonderfully with roasted meats, grilled chicken, or even a light salad for a complete meal.

### Tips for Perfecting Your Sweet Potato Casserole:

– **Make it Ahead:** This casserole can be assembled a day in advance and stored in the refrigerator. When ready to bake, simply pop it in the oven and bake as directed. This is a great option for busy days or holiday meals where you want to save time.
– **Use Your Favorite Cheese:** While this recipe calls for cheddar and mozzarella, you can mix and match your favorite cheeses. Gruyère, gouda, or even a spicy pepper jack can add an interesting twist to the flavor.
– **Add Crunch:** For a little extra texture, sprinkle some crushed crackers or breadcrumbs on top before baking. This will give the casserole a nice crispy topping that contrasts beautifully with the creamy interior.
– **Boost the Flavor:** Add a dash of cayenne pepper or paprika for a little kick, or mix in some crumbled bacon or sausage for a savory addition.
