Organic Zucchini and Squash Au Gratin Recipe (2024)

Is A Zucchini A Fruit or Vegetable?

Have you ever wondered if a zucchini or squash was a fruit or vegetable? I have, and really it tastes so amazing that I really never worried too much about it.

But for those of you who really want to know, zucchini and squash are technically a fruit. But in the culinary world, they are considered a vegetable.

In most culinary kitchens, savory typically means vegetable and sweet carries the word fruit. Just a fun tidbit to know.

Growing Your Own Zucchini and Squash

Some of my all time favorite vegetables to grow in my garden are zucchini and squash plants. They are super easy to grow and they produce plenty of fruit for the whole family to enjoy.

Oftentimes, people run into a few challenges when growing vine like plants and the problems are actually super easy to solve!

This season I have done two posts on my other site, Growing Real Food, on how to conquer problems that might arise when growing zucchini and squash.

If you are a gardener, be sure to check these two post out.

Description

Once you dive into this delicious and easy Au Gratin recipe, I can assure you it will go into your regular rotation for hitting your families dinner table!

Ingredients

6 tbsp butter
3 large Vidalia onions (sweet onions) cut sliced
1 pound zucchini (2 medium), sliced 1/4″ thick
1 pound yellow squash (2 medium), sliced 1/4″ thick
2 tsp sea salt
1/2 tsp black pepper
1/4 tsp freshly ground nutmeg
2 tbsp organic all purpose flour, rice flour, or oat flour
1 cup organic milk
2 slices bread (I used a real sourdough bread), toasted, cooled and ground up into fine bread crumbs
1/2–3/4 cup grated parmesan cheese
1 tbsp butter, melted to drizzle on casserole (optional)

Instructions

Preheat oven to 400ºF oven.
In a large skillet that has a lid, preheat the pan over low heat.
Melt the butter and add onions and cook very slowly for 20 minutes or until soft and tender but not brown. By cooking very slowly the onions become sweeter.
When the onions are soft add the zucchini and squash, stir and place a lid on the pan and cook covered for 10 minutes, stirring occasionally.
After 10 minutes, remove lid and add the salt, pepper and nutmeg and cook another 5 minutes uncovered.
Stir in flour and milk and stir until bubbly and the sauce starts to thicken (about 2 minutes.)
Pour mixture into a ungreased 9″x13″ dish.
Stir together the bread crumbs and parmesan cheese and sprinkle mixture onto casserole.
If desired drizzle a tablespoon or two of melted butter over the bread crumb mixture.
Bake for 20 minutes or until nice and bubbly and slightly browned.
