Spinach Potato Casserole
Why It's Yummy
This spinach potato casserole is everything you want in a comfort food dish-rich, creamy, and packed with flavor.
The combination of tender baby potatoes, fresh spinach, and gooey melted cheese makes it irresistible.
Plus, it's a healthier take on traditional creamy casseroles, with fresh ingredients and simple seasonings.
Ingredients
- Baby potatoes - I always boil them with the skins on for extra texture and nutrients. Plus, less peeling means less work!
- Cooking oil - I like avocado or olive oil for a healthy touch and a hint of flavor.
- Onion - Adds depth of flavor and a slight sweetness when sautéed. A must-have for building a great base.
- Fresh spinach leaves - a great way to sneak in extra greens without overpowering the dish!
- Garlic - Freshly minced or pressed for the best flavor. Don't skimp-garlic makes everything better.
- Sour cream - Adds creaminess and tang, balancing out the richness.
- Salt & black pepper - I recommend freshly ground black pepper for extra aroma.
- Italian seasoning - A mix of dried herbs that brings everything together. If you have fresh herbs, even better!
- Paprika - I love using smoked paprika for extra depth and a hint of warmth.
- Mozzarella - Melts beautifully for that gooey, cheesy topping. If you want a sharper bite, try a mix of cheeses.
- Cream cheese - This is my secret to that ultra-creamy texture. You can also use more sour cream or thick plain yogurt but flavor and texture will be different.
- Green onion or parsley - For garnish and a pop of freshness. A little bit makes a big difference!

Tips
- Use different potatoes. Yukon Golds or red potatoes work great if you don't have baby potatoes.
- Make it extra cheesy. Add a mix of cheddar or Gruyère for a deeper flavor.
- Swap the spinach. Kale or Swiss chard are great alternatives.
- Add protein. Mix in cooked chicken or crumbled bacon for a heartier dish.
- Make it dairy-free. Use dairy-free sour cream and cheese substitutes.
- Prep ahead. Boil the potatoes a day in advance to save time.
- Spice it up. A pinch of red pepper flakes adds a little kick.
- Use fresh herbs. Try fresh basil or thyme for extra flavor.
- Make it crispy. Add a layer of panko breadcrumbs on top before baking.
- Double the batch. Perfect for meal prep or larger gatherings.
