Ingredients List

Save

• 2 tablespoons butter (grass-fed preferred for extra nutrients)
• 2 large eggs, beaten
• 8 oz cream cheese, softened (full-fat for best keto macros)

• ½ cup sour cream (can substitute with full-fat Greek yogurt)
• 2 tablespoons heavy cream
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• ½ teaspoon dried thyme (fresh works too – use 1½ teaspoons)

• ¼ teaspoon black pepper (freshly ground enhances flavor)
• ¼ teaspoon cayenne pepper (optional for heat lovers)
• ½ cup pork rinds, crushed (for crispy topping)
• ¼ cup parmesan cheese, grated (for topping)

Step-by-Step Instructions

Save

Step 1: Prepare Your Squash

Preheat your oven to 350°F (175°C). Slice your yellow squash into ¼-inch rounds. Avoid cutting them too thin as they’ll become mushy during cooking. If your squash is particularly large, you may want to halve the rounds for more even cooking.

Step 2: Pre-Cook the Vegetables

In a large skillet over medium heat, melt the butter. Add the diced onion and sauté until translucent, about 3-4 minutes. Add the sliced squash and cook for 5-7 minutes until the squash begins to soften but still maintains some firmness. Season with a pinch of salt to help release moisture.

Step 3: Drain Excess Moisture

This is a crucial step for a keto squash casserole that isn’t watery! Transfer the cooked squash mixture to a colander and press gently with paper towels to remove excess moisture. Let it cool for about 5 minutes.

Step 4: Prepare the Creamy Base

In a large mixing bowl, combine the softened cream cheese, sour cream, heavy cream, beaten eggs, garlic powder, onion powder, dried thyme, salt, black pepper, and cayenne (if using). Mix until smooth and well incorporated. This creates the rich, creamy foundation of your casserole.

Step 5: Combine and Assemble

Add the drained squash and onion mixture to the cream cheese mixture. Fold in the shredded cheddar cheese, being careful not to mash the squash. Transfer the entire mixture to a greased 9×13 inch baking dish, spreading it evenly.

Step 6: Create the Crispy Topping

In a small bowl, combine the crushed pork rinds and grated parmesan cheese. Sprinkle this mixture evenly over the top of the casserole. This will create a deliciously crispy, golden crust that adds wonderful texture contrast to the creamy casserole.

Step 7: Bake to Perfection

Bake in the preheated oven for 25-30 minutes, until the top is golden brown and the edges are bubbling. For an extra golden top, broil for the final 2 minutes, watching carefully to prevent burning.

Step 8: Rest and Serve

Allow the casserole to rest for 10 minutes before serving. This resting period helps the casserole set up properly and makes it easier to serve neat portions. Garnish with fresh chopped parsley for a pop of color and fresh flavor.

Healthier Alternatives for the Recipe

While this recipe is already keto-friendly, here are some modifications to suit various dietary needs:

• Dairy-Free Option: Replace cream cheese with dairy-free cream cheese alternative, use coconut cream instead of heavy cream, and substitute nutritional yeast for the cheese in the topping.
• Lower Calorie Version: Use light cream cheese and reduce the amount of cheddar by half. Increase the proportion of squash for more volume with fewer calories.
• Vegetable Variations: Mix in 1 cup of spinach or kale for added nutrients and color without significantly increasing carbs.
• Protein Boost: Add 2 cups of shredded rotisserie chicken or 1 pound of browned ground turkey for a complete meal option.
• Nut-Free Topping: If avoiding pork rinds, use a mixture of almond flour and parmesan (if nuts are acceptable) or just increase the parmesan for the topping.

Serving Suggestions

Elevate your keto squash casserole experience with these complementary serving ideas:

• Pair with a simple grilled protein like chicken thighs, steak, or salmon for a complete keto meal.
• Serve alongside a fresh green salad dressed with olive oil and lemon for a refreshing contrast to the rich casserole.
• For brunch, top each portion with a perfectly poached egg for added protein and a luxurious presentation.
• Transform leftovers by reheating with additional cheese on top and serving in lettuce cups for a fun lunch option.
• For entertaining, portion into small ramekins for individual servings that make an elegant presentation.

Common Mistakes to Avoid

1. Skipping the draining step: Yellow squash contains significant moisture. Failing to drain properly results in a watery casserole. Press firmly with paper towels to remove excess liquid.
2. Overcooking the squash initially: The squash will continue cooking in the oven. If you cook it until completely soft in the skillet, it will become mushy in the final dish.
3. Using cold ingredients: Cold cream cheese won’t blend smoothly. Ensure cream cheese is properly softened at room temperature for about 30 minutes before mixing.
4. Cutting squash unevenly: Inconsistent slices lead to uneven cooking. Aim for uniform ¼-inch thickness for best results.
5. Rushing the cooling period: Serving immediately after baking results in a runny casserole. The 10-minute rest is essential for proper setting.

Storing Tips for the Recipe

Make the most of your keto squash casserole with these storage recommendations:

• Refrigeration: Store leftovers in an airtight container for up to 4 days. The flavors often improve overnight as they meld together.
• Freezing: This casserole freezes beautifully for up to 3 months. Portion into individual servings before freezing for easy reheating. Thaw overnight in the refrigerator before reheating.
• Reheating: For best texture, reheat in a 325°F oven for 15-20 minutes until heated through. Microwave reheating works but may result in a slightly softer texture.
• Make-Ahead Option: Prepare the entire casserole up to the baking step, cover, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time when cooking from cold.
• Topping Tip: If making ahead, add the pork rind topping just before baking to maintain its crispness.

Conclusion

This keto squash casserole transforms simple ingredients into a decadent, satisfying dish that perfectly aligns with low-carb lifestyle goals. With its creamy texture, crispy topping, and versatile serving options, it proves that comfort food can absolutely be part of a ketogenic diet.
