Ingredients for Your Keto Squash Casserole
Gather these simple ingredients:
- 2 lbs yellow squash, sliced very thinly (aim for about 1/8-inch thick slices). This ensures they cook evenly and become wonderfully tender.
- 1 cup shredded cheddar cheese. Sharp cheddar gives a great flavor punch!
- 1/2 cup sour cream. This adds a lovely tang and creaminess.
- 1/4 cup mayonnaise. It helps bind everything and adds richness.
- 1/4 cup finely chopped yellow onion. A little onion adds a subtle sweetness.
- 2 large eggs, lightly beaten. These act as a binder for the casserole.
- 1/4 cup grated Parmesan cheese. For that extra salty, nutty top layer!
- Salt, to taste. Just enough to enhance all the flavors.
- Black pepper, to taste. A little pepper wakes everything up.
Equipment You’ll Need for Keto Squash Casserole
You won’t need much:
- A large mixing bowl.
- A whisk or fork for beating eggs.
- Measuring cups and spoons.
- A sharp knife or mandoline slicer for your squash.
- A 9×13 inch baking dish.
- Oven mitts for safe handling.
How to Prepare Your Keto Squash Casserole
Let’s get cooking!
Step 1: Preheat and Prepare
First, preheat your oven to 375°F (190°C). Make sure your 9×13 inch baking dish is lightly greased. This stops anything from sticking.
Step 2: Combine the Casserole Ingredients
In your large mixing bowl, add the thinly sliced yellow squash. Then, toss in the shredded cheddar cheese, sour cream, and mayonnaise. Add the finely chopped onion and the lightly beaten eggs. Sprinkle in the grated Parmesan cheese.
Step 3: Seasoning and Mixing
Season everything generously with salt and pepper. Gently mix all the ingredients together until they are well combined. Be careful not to overmix, as you don’t want to mash the squash.
Step 4: Transfer to Baking Dish
Carefully pour the squash mixture into your prepared baking dish. Spread it out evenly so it bakes uniformly.
Step 5: Bake to Perfection
Place the baking dish in the preheated oven. Bake for about 30 to 40 minutes. You’re looking for the casserole to be set and have a lovely light golden-brown color on top. The edges should be bubbling gently.
Step 6: Rest Before Serving
Once it’s done, carefully remove the casserole from the oven. Let it sit for about 5-10 minutes before serving. This helps it set up nicely.
Ingredient Notes and Substitutions for Keto Squash Casserole
About the Squash
Yellow squash is lovely here, but you can also use zucchini or a mix of both! Just make sure to slice them thinly for even cooking.
Cheese Variations
Feel free to swap the cheddar for Monterey Jack, Gruyere, or a blend of your favorite keto-friendly cheeses. Each will give a slightly different flavor profile.
Creaminess Adjustments
If you prefer a richer, creamier casserole, a tablespoon or two more of sour cream or mayonnaise works wonders. You can also add a splash of heavy cream.
Tips for the Perfect Keto Squash Casserole
Here are a few tricks:
- Even Slicing is Key: Thin, uniform slices mean everything cooks at the same rate.
- Don’t Overmix: Gently combine ingredients to keep the squash texture nice.
- Watch for Browning: If the top is browning too quickly, you can loosely tent it with foil.
Serving Suggestions for Your Keto Squash Casserole
This casserole is a fantastic side dish. It pairs wonderfully with grilled chicken, steak, or pork chops. It also makes a great accompaniment to a hearty green salad for a lighter meal.
Storing and Reheating Your Keto Squash Casserole
Leftovers are delicious!
Refrigeration
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. It holds its shape well.
Freezing
You can also freeze portions. Let the casserole cool completely, then wrap individual servings tightly. It should keep for about 1-2 months.
