Tips for Perfect Filling Mexican Sweet Potato Quinoa Casserole
- Roast first: Roasting the sweet potatoes before baking adds flavor and keeps the texture perfect.
- Use broth for quinoa: It infuses extra flavor and prevents blandness.
- Make it vegan: Just swap out the cheese for your favorite dairy-free version.
- Add extra veggies: Bell peppers or spinach fit right in.
Small touches like these are what make dishes like my Cottage Cheese Beef Noodle Bake and Sweet Potato & Lentil Shepherd’s Pie so delicious — it’s all about building layers of flavor.
