Main Ingredients

Fat Sources

2 tablespoons Butter (regular or vegan)

•     Adds richness and flavor; helps sauté the onions and garlic. Alternatively, you can substitute with olive oil or vegetable oil of your choice, like avocado oil, coconut oil or your preferred vegetable oil for making low-carb casseroles.

1/2 cup Heavy Cream (or unsweetened full-fat coconut milk for a vegan option)

•     Contributes to the creamy texture of the casserole. The heavy whipping cream texture gives the spinach casserole its rich and creamy texture.

1/4 cup Milk (or unsweetened full-fat coconut milk for a vegan option)

•     Adds creaminess; balances the thickness of the sauce.

Cheese & Cream ingredients

4 oz Cream Cheese (softened, or cashew cream cheese for a vegan option)

•     Gives a rich, creamy texture; enhances the cheesy flavor.

1 1/2 cups Shredded Monterey Jack Cheese (or Pepper Jack, or vegan shredded cheese with 4 tablespoons nutritional yeast)

•     Melts into the casserole, adding a cheesy, gooey texture. The cheese topping will become wonderfully golden brown as the easy keto casserole bakes.

Aromatics & Seasonings

1 medium Onion (finely chopped)

•     Adds a sweet, savory flavor; complements the richness of the cheese.

3 cloves Garlic (minced)

•     Infuses the dish with a robust, aromatic flavor.

1/2 teaspoon Salt

•     Enhances the overall flavor of the dish.

1/4 teaspoon black Pepper

•     Adds a hint of spice.

1 teaspoon Italian Seasoning Blend (or Herb de Provence)

•     Brings a mix of herbs for a fragrant and flavorful profile.

1/4 teaspoon Grated Nutmeg (optional)

•     Adds a warm, slightly sweet undertone that pairs well with spinach.

Optional Garnish

1 Handful Fresh Basil (for garnish)

•     Adds a fresh, vibrant touch to the finished dish.

These ingredients come together to create a rich, creamy, and cheesy casserole that’s both satisfying and easy to prepare.

Best spinach casserole recipe tips and tricks 

Here are some easy tips to enhance your egg free spinach casserole:

1. Squeeze the Spinach Dry: If using frozen spinach, be sure to squeeze out as much moisture as possible. This helps to make the casserole thicker and prevents it from becoming too watery.

2. Add a Pinch of Nutmeg: For a subtle depth of flavor, add a pinch of nutmeg. This classic tip from my grandmother enhances the overall taste of the casserole.

3. Spice It Up: For a kick of heat, incorporate cayenne pepper or chili flakes. Adjust the amount based on your spice preference to add a flavorful punch.

4. Use Vegan Alternatives: To make a vegan keto spinach casserole, use full-fat coconut milk and cashew cream cheese. These substitutes will keep the casserole creamy and delicious while adhering to your dietary needs.

5. Meal Prep for Convenience: Prepare the casserole in advance and store it in the refrigerator or freezer. This makes it easy to have a ready-to-eat meal throughout the week, saving you time and effort.

How to store and reheat healthy creamy spinach casserole 

How to Meal Prep the Creamy Spinach Casserole

1. Prepare in Advance: 

   – Follow the recipe instructions to mix the ingredients and assemble the casserole in your baking dish.

   – Instead of baking it right away, cover the assembled casserole tightly with plastic wrap or aluminum foil.

   – Store it in the refrigerator for up to 2 days before baking.

2. Batch Cooking:

   – You can double or triple the recipe and divide it into multiple smaller baking dishes. This way, you can bake one now and save the others for later in the week or freeze for a longer period.

3. Portion Control:

   – After baking, divide the casserole into individual portions using meal prep containers. This makes it easy to grab and go during the week.

How to Store the Creamy Spinach Casserole

1. In the Refrigerator:

   – After baking, let the casserole cool to room temperature.

   – Cover the baking dish tightly with plastic wrap or aluminum foil, or transfer the casserole to an airtight container.

   – Store it in the refrigerator for up to 3-4 days.

2. In the Freezer:

   – To freeze, allow the casserole to cool completely after baking.

   – Wrap the entire dish tightly in plastic wrap and then in aluminum foil, or transfer it to a freezer-safe airtight container.

   – Label the container with the date and store it in the freezer for up to 2-3 months.

   – If freezing in portions, divide the casserole into individual portions before freezing for easier reheating.

How to Reheat the Creamy Spinach Casserole

1. From the Refrigerator:

   – In the Oven: Preheat the oven to 350°F. Cover the casserole with aluminum foil to prevent it from drying out. Reheat for 15-20 minutes, or until heated through.

   – In the Microwave: Place a portion of the casserole on a microwave-safe plate. Cover with a microwave-safe lid or another plate. Heat on medium power for 1-3 minutes, checking every 30 seconds until it’s warmed through.

2. From the Freezer:

   – In the Oven: It’s best to thaw the casserole overnight in the refrigerator before reheating. Once thawed, preheat the oven to 350°F. Cover with foil and bake for 20-30 minutes, or until heated through. If reheating directly from frozen, increase the baking time to 45-60 minutes.

   – In the Microwave: If reheating from frozen, use the defrost setting on your microwave first, then heat as usual.

By following these steps, you can easily meal prep, store, and reheat your healthy, creamy spinach casserole, making it a convenient and delicious option for your keto meal plan!
