Grab a saucepan, preferably one with high sides.

Crank the burner up to medium to high heat.

Pour in 2 tablespoons or 30 milliliters of a neutral oil of your choice.

Once the oil is hot, drop in one large sweet onion, chopped.

Saute the onions until tender and lightly brown around the edges.

At the tail end of cooking the onions, add a dash of nutmeg and 1/4 teaspoon of ground mustard.

Stir and let it cook for about 30 seconds.

Move all of the onions to the side of the pan, making a well in the center.

Turn the heat to medium and add 2 tablespoons or 28 grams of unsalted butter to the center of the pan.

Melt the butter down, then add 4 tablespoons or 32 grams of all purpose flour to create a roux.

Mix the flour and butter together, then combine it with the onions.

Cook the mixture for approximately two minutes, stirring frequently, and adjust the heat if necessary.

Add 2 cups or 500 milliliters of milk and 1 cup or 250 milliliters of heavy cream to the roux.

Crank the burner up to medium heat and bring it back to a simmer, stirring frequently.

Once it begins to simmer and thicken, simmer it for a few minutes until it coats the back of the spoon.

Reduce the heat to low and add 1 cup or 100 grams of freshly grated Parmesan cheese, stirring to combine.

Taste the sauce and adjust seasoning with salt or black pepper if necessary.

Add 3 pounds of chopped frozen spinach, thawed and wrung out, to the sauce in batches.

Stir everything over low heat until well mixed together.

Transfer the spinach mixture to a baking dish.

Top with 1 cup or 100 grams of freshly grated Gruyere cheese.

Bake in a preheated oven at 425 degrees Fahrenheit for approximately 20 minutes, until bubbly and lightly golden brown.
