Step‑by‑Step Instructions for Skinny Cheesy Potato Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms, prepare a 3-quart or 9x13-inch casserole dish by spraying it with cooking oil to prevent sticking. This ensures your Skinny Cheesy Potato Casserole will slide out easily when it’s ready to serve.
Step 2: Boil the Potatoes
Cut the Russet potatoes in half and place them in a large pot of salted water. Bring the water to a boil and cook the potatoes for 8-10 minutes, or until they are nearly tender but not fully soft. Once done, drain them in a colander and let them cool briefly before handling for the next step.
Step 3: Grate the Potatoes
Using the largest grate on a box grater, shred the cooled potatoes into a large bowl. This ensures even texture throughout your Skinny Cheesy Potato Casserole. The shredded strands will create a delightful cheesy pull once baked, so make sure to take your time to achieve the right consistency.
Step 4: Mix the Creamy Base
In a separate large mixing bowl, whisk together the melted butter, low-fat cream cheese, Greek yogurt, low-fat milk, kosher salt, and freshly ground black pepper until the mixture is completely smooth and blended. This creamy base adds richness to your casserole, balancing the healthy ingredients while keeping it indulgent.
Step 5: Combine Ingredients
Gently fold the shredded potatoes into the creamy mixture, ensuring all the strands are coated. Stir in the chopped green onions and half of the shredded mozzarella and cheddar cheese, mixing well to combine all the flavors. This will create a delightful and cheesy filling for your casserole.
Step 6: Assemble the Casserole
Pour the potato mixture into your prepared casserole dish, spreading it evenly to ensure an even bake. Sprinkle the remaining mozzarella and cheddar cheese generously over the top. This layer will melt beautifully, creating a golden-brown crust that’s hard to resist once baked.
Step 7: Bake to Perfection
Place the casserole in the preheated oven and bake for about 30 minutes or until the cheese is melted, bubbly, and golden. Keep an eye on it towards the end to avoid over-browning. The enticing aroma of your Skinny Cheesy Potato Casserole will fill your kitchen, promising a comforting and satisfying meal.

Make Ahead Options
These Skinny Cheesy Potato Casserole preparations are a fantastic solution for busy home cooks looking to save time! You can prepare the entire casserole up to 24 hours in advance, making it perfect for meal prep. Simply follow all the steps until assembling the casserole, then cover it tightly with plastic wrap or foil and refrigerate. Just before serving, let the casserole sit at room temperature for about 30 minutes to ensure even heating, then bake it as instructed. This way, not only will you cut down on cooking time, but you’ll also enjoy the same creamy, cheesy goodness without compromising quality!
Storage Tips for Skinny Cheesy Potato Casserole

Skinny Cheesy Potato Casserole Recipe FAQs
How do I choose the best Russet potatoes for this recipe?
Absolutely! Look for medium-sized Russet potatoes that feel firm and have no dark spots or blemishes. They should be uniform in size for even cooking. Choose potatoes that are heavy for their size, indicating they are fresh and have a good moisture content.
How should I store leftovers from the Skinny Cheesy Potato Casserole?
Once cooled, store leftover casserole in an airtight container in the refrigerator for up to 3 days. Make sure to let it cool completely before sealing to avoid condensation, which could make it soggy. The flavors will continue to develop while stored!
Can I freeze the Skinny Cheesy Potato Casserole?
It's not recommended to freeze this casserole. The high dairy content can alter the texture upon thawing, which may result in a watery consistency. However, if you’re looking to prepare ahead, refrigerate and bake it fresh when you’re ready to enjoy!
What should I do if my casserole is too dry after baking?
If your casserole turns out drier than expected, you can add a splash of low-fat milk to restore creaminess. Just drizzle it over the top and gently mix before baking it for another 5-10 minutes. This will help reintroduce moisture and improve the dish's overall texture.
What dietary considerations should I keep in mind for this casserole?
I often suggest considering any allergies in your family. For a gluten-free version, ensure all your ingredients, especially any spices or broths, are labeled gluten-free. Additionally, you can replace the low-fat cream cheese and Greek yogurt with vegan options to make it dairy-free, perfect for plant-based eaters!
