What is Asparagus Gratin?
Gratin is the crust formed at the top of baked dishes. When you think of a baked casserole and the corner pieces which have those slightly burnt edges and deep flavor, that is what gratin aims to do.
A classic French dish, gratins are typically made with cheese, breadcrumbs, and cream. Today, its found in many family kitchens throughout America and parts of Europe, especially on holidays.
You've probably heard of potato au gratin or mushroom gratin. Asparagus gratin simply uses asparagus as the base
How This Recipe Compares With Other Asparagus Gratin
This lightened-up asparagus gratin recipe is gluten-free. Rather than panko bread crumbs, we make our own with Bread SRSLY's gluten-free sourdough, which is a bit tangier and heartier. With our sourdough breadcrumbs, no opportunity for flavor is left unturned.
We keep this recipe easy by skipping the step of making a roux or béchamel sauce, avoiding the need for a hot pan. Instead, we use coconut flour to thicken the milk, creating a light cream sauce. And rather than using wheat flour like typical recipes, our coconut flour keeps this gluten-free.
How This Recipe Compares Nutritionally
Our asparagus gratin recipe has about half the calories of others, on average. This is in part by using a low fat milk instead of cream or whole milk, and in part by forgoing butter.
Cheese provides the rich fatty flavor desired in gratin. Though, the saturated fat content in our recipe is much lower than in others, making it a great side choice for those who prefer a low-fat diet.
