How to make healthy squash casserole
This healthy squash casserole recipe is probably the easiest one you can try. All you have to do is add layers of ingredients and bake. It can’t be any simpler. Here are the steps you have to follow:
- Start by preparing the yellow squash. Do that by washing it and slicing it in equal slices. Place these slices in a pot and pour vegetable stock on top until it covers the vegetable. Place the pot on medium heat and bring it to a boil. Let it simmer for 5 minutes or until the vegetable is tender. Drain and set aside.
- To prepare the vegan cheese sauce, you will have to add soaked cashews, water, red bell pepper, nutritional yeast, onion powder, garlic powder, cayenne pepper, and salt in a high-speed blender jug.
- Blend until you get a smooth consistency sauce. You can add more water if the sauce is too thick. Now the vegan sauce is ready.
- Grease a casserole pan with coconut oil. Layer cooked yellow squash slices in the bottom of the casserole pan. Pour vegan cheese sauce on top. Cover with breadcrumbs and add a vegan button on top.
- Step 5: Place the casserole pan in a preheated oven at 400-degree f for 15 minutes or until you get a golden-brown top.
Expert Tips
Although making this healthy squash casserole is very easy, you still need to take care of a few things:
- You can also add sliced zucchini or eggplant to add more flavor and color to the casserole.
- If you don’t have vegetable broth, use vegetable bouillons dissolved in water. It will give the same flavor.
- Soaking cashews is important for the texture of the vegan cheese sauce. If you don’t soak cashews, the sauce will be grainy. The more you soak them. The better will be the sauce’s texture.
- You can add black pepper, paprika, or red chili flakes instead of cayenne.
- You can use vegan butter instead of coconut oil.
- For the extra crunchy top, broil for 5 minutes.
- You can bake this casserole in an air fryer as well.
Variations and Substitutions
Herb Infusion: Add fresh or dried herbs like thyme, rosemary, or basil to the vegan cheese sauce for extra flavor.
Garlic Lovers: If you’re a fan of garlic, consider adding roasted garlic cloves or minced garlic to the cheese sauce for a robust flavor.
Extra Veggies: Enhance the nutritional content by incorporating other veggies like zucchini, bell peppers, or spinach along with the yellow squash.
Storage Tips
Refrigerator
Store the leftover squash casserole by placing it in an airtight container and storing it in the refrigerator. It will last for up to 5 days.
Freezer
Furthermore, you can also freeze the leftover squash casserole. Place it in aluminum foil or plastic Ziplock bag and freeze. It will last for up to 2 months in the freezer.
You can also freeze uncooked squash casserole. Place it in a freezer-safe and oven-safe dish and freeze. It will last for up to a month. You can cook it directly without thawing. It might take a bit longer, but it is super convenient.
Recipe FAQs
First, look at the color of the squash. It should be completely yellow with no green or brown spots. It should also have a firm texture and should not feel hollow inside. Last, make sure the stem is firm and dry.
While this recipe specifically calls for yellow squash, you can certainly use other types of summer squash, such as zucchini or pattypan squash, or a combination of different squashes.
Nutritional yeast contributes to the cheesy flavor of the sauce. If you prefer to omit it, you’ll lose some of the cheesy taste, but the sauce will still be flavorful.
