How to Make Zucchini Casserole Recipe:

Prep: Preheat oven to 400˚F and butter a 9×13 baking casserole dish.

1. Grate zucchini on the large holes (the grating attachment on a food processor makes it so easy!). You should get 7 to 8 cups before squeezing dry. Transfer grated zucchini to a colander over the sink and stir in 1 tsp salt. Let stand for 10 min, stirring a couple of times then squeeze out the excess moisture with your hands. Transfer drained zucchini to a large mixing bowl.

2. Mix 2/3 cup of sour cream with 1/2 tsp baking powder and let it stand while zucchini drains (8-10 min).

3. Into the mixing bowl with drained zucchini, stir in 4 eggs and sour cream mixture.

4. Add cooked rice and 2 cups shredded cheese. Stir in 1/2 cup chives, 1/2 tsp salt and 1/2 tsp Mrs. Dashseasoning.

5. Pour mixture into buttered casserole dish and lightly spread 1/3 cup sour cream over the top. Sprinkle remaining 1 cup of cheese over the surface and bake uncovered in the center of your oven at 400˚ for 40 min. Let it stand for 10 min before serving.
