When I used to garden, I had a whole cookbook devoted to summer squash and zucchini recipes. These are some ideas:
Breakfast:
Summer Squash/Zucchini Omelet
Summer Squash/Zucchini Muffins/Quick Breads with or without chocolate or nuts
Appetizers:
Summer Squash/Zucchini Bread and Butter Pickles
Summer Squash/Zucchini Soup with Corn or Cheese
Summer Squash/Zucchini Pancakes/Fritters
French/Deep Fried Squash/Zucchini Chips/Sticks
Main Dishes:
Summer Squash/Zucchini Quiche
Stuffed (I have successfully used ground meats: bulk sausage, hamburg, chicken, turkey, shrimp, crab, clams and smoked fish for the protein.)
Side Dishes:
Ratatouille
Summer Squash/Zucchini Sauteed with Tomatoes and Corn
Casserole (one has a sleeve of saltine crackers in it; another has cheddar cheese cubes and cherry/grape tomatoes)
Desserts:
Cake (There are all sorts of variations, I always preferred the chocolate ones. The shredded summer squash/zucchini makes the cake unbelievably moist.)
Cookies
Additionally, if you were lucky to receive any small ones (the size of your middle finger or smaller) throw them in boiling water for a quick dip, followed by an ice bath; then spin them, dry them, put them on a cookie sheet to freeze and them bag them up in freezer bags to use again in late fall/early winter. I found that freezing bigger ones that have developed seeds resulted in mush!
Finally, when I am searching for recipes I usually start out at
