What do you need to make our creamy spinach gratin?

For this recipe, you will need one large heavy bottom skillet to saute the onion and garlic, then the spinach, and add the cream mixture. Plus, one 8 x 8-inch baking pan to bake it in.

Ingredients Needed for our Spinach Gratin…

For our spinach gratin, you will need the following ingredients:

(*Exact measurements for ingredients in recipe card below!)

  • OLIVE OIL: choose good quality olive oil, we prefer to use extra virgin olive oil with most of our recipes.
  • VEGETABLES: medium-sized onion and a couple of garlic cloves are all you need to flavor the spinach.
  • BABY SPINACH: This recipe calls for fresh baby spinach (3 packages of 6 ounces each, about 2 .25 pounds/510 grams).
  • FLOUR: you will need a 2 tablespoons of all-purpose flour to thicken the cream sauce. If needed, use GF flour, with this recipe too!
  • CREAM: 1/2 cup of heavy cream is added to make the cream sauce.
  • BROTH: some vegetable broth (about 1/2 cup) is needed to flavor the sauce.
  • SEASONINGS: 1/8 tsp. of ground nutmeg, 2 dashes of cayenne pepper, and 1 tsp. of salt are all you will need for this recipe.
  • CHEESES: I used 3 different kinds of cheeses: (2/3 cup divided of grated Parmesan cheese, 2 Tbsp. of grated pecorino, and 1/2 cup of shredded Gruyere.
  • OPTIONAL: make it extra special, and scatter a layer of panko bread crumbs on top. It offers the perfect little crunch on top of the gratin.

Questions & Answers…

  • Is this a Gratin or a Casserole? There is a slight difference between a casserole and a gratin. While both are baked in the oven, a gratin is a special form of a casserole. When cooking it, the ingredients are layered instead of just adding them all together.
  • Can we make it gluten-free? You can substitute flour with gluten-free flour, or cornstarch. Be sure to use equal amounts.
  • Can we make it with frozen spinach? If you prefer to make this gratin with frozen spinach you can. Use 2 packages of (10-ounces) frozen spinach, thawed and drained. Then follow our directions.
  • Are there options to use different cheeses? You can use other grated or shredded cheeses like Mild Cheddar, Swiss, and even Mozzarella cheese. They will all work nicely.

Notes

QUICK NOTE: The Nutritional Facts do include the panko bread crumbs.

Also, if you rinse and drain fresh spinach, ADD the wet spinach to the skillet. It needs the moisture to wilt it quickly.

If the spinach is not wet, add a few drops of water to the skillet, cover with a lid, to help the spinach to wilt quickly.
