Ingredients

  • 2 zucchini squash, sliced
  • 2 yellow squash, sliced
  • 1 onion, chopped
  • 1/2 stick butter
  • 1 package Hidden Valley Ranch dressing
  • 1 cup cheese
  • 1/2 cup mayonnaise
  • 1 egg

Instructions

  1. Stir-fry the sliced zucchini, yellow squash, and chopped onion in butter until slightly tender but still crisp.
  2. Combine the cooked vegetables with the remaining ingredients: ranch dressing, cheese, mayonnaise, and egg.
  3. Transfer the mixture to a casserole dish.
  4. Top with Atkins chips and additional cheese.
  5. Bake at 350°F for 30 minutes until bubbly and golden.

Tips & Substitutions

For a creamier texture, consider adding a bit of cream cheese or Greek yogurt along with the mayonnaise. If you're looking for a lower-fat option, substitute the butter with olive oil or a cooking spray. You can also use a different cheese, such as feta or mozzarella, to change the flavor profile. For an added crunch, top with crushed pork rinds instead of Atkins chips.

Serving Suggestions

This casserole is delicious served as a main dish or as a side to grilled meats, like chicken or steak. It pairs beautifully with a fresh garden salad for a light meal. For a heartier option, consider serving it alongside roasted vegetables or a slice of crusty low-carb bread. This dish also makes a great addition to a potluck or family gathering.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a microwave-safe dish and cover; heat for 1-2 minutes or until warmed through. Alternatively, you can reheat in the oven at 350°F for about 15-20 minutes, covered with foil to prevent drying.
