Ah, Zucchini Jack Casserole. I loved it when I was a teenager, and I still adore it today. The squash is suspended in a voluptuous Monterey Jack cheese custard that puffs up in the oven. And should I mention the casserole’s crunchy crouton crown? Here’s the recipe for this creamy and comforting 1970s classic:
Note: I wrote about this casserole during the dark days of this blog. The following version includes step-by-step photographs and a 1-click printable recipe.
Take six small zucchinis (1 1/2 to 2 pounds total)…
And slice ’em into 1/4-inch rounds.
Then mince up a garlic clove…
And chop up a small onion.
Chop up some parsley, too — enough to equal 1/4 cup.
Now put 3 tablespoons of butter in a medium bowl, and heat in the microwave until melted — about 30 seconds.
To the butter, add 1 1/2 cups of small, seasoned croutons…
And toss with a spatula to coat.
Let’s assemble our Zucchini Jack Casserole!
Break 5 large eggs into a big mixing bowl…
And whisk them to smithereens.
Now whisk in 1/2 cup milk…
1 teaspoon salt…
2 teaspoons baking powder…
And 3 tablespoons flour.
Then trade your whisk for a big spoon, and use it to stir in the garlic, onion, and parsley.
Now stir in a large (7 ounce) can of chopped green chiles…
And an ungodly amount of shredded Monterey Jack cheese — about 4 cups of it.
Add the zucchini rounds, and stir to coat.
Then transfer the goods to a greased 9×13 baking dish, and scatter the croutons over the top!
Bake the casserole at 350°F until puffed and golden — about 50 minutes. Let cool for 10 minutes.
