Easy To Make Oyster and Spinach Gratin

Easy To Make Oyster and Spinach Gratin

An easy oyster gratin that can be made in just one frying pan and then baked. The umami that comes out of the oysters is so good!

Ingredients: 2 to 3 servings

Shucked oysters
about 130 g (1 packet)
Spinach
1 bunch
Shimeji mushrooms
1 packet
Onion
1/2
Bacon
2 slices
Butter
2 tablespoons
Plain flour
3 tablespoons
Milk
2 cups
Soup stock
1 cube
Salt and pepper
to taste
Easy melting cheese
to taste

Steps

1. Rinse the oysters in salted water and drain. (If you are using frozen oysters you can use them as-is.) Cut the bacon up.
2. Boil the spinach briefly, drain and refresh in cold water. Squeeze out excess water and cut into pieces. Slice the onion thinly, and loosen the shimeji mushrooms apart.
3. Spread 1 tablespoon of olive oil in a frying pan, and sauté the bacon, then the onions. Add the shimeji mushrooms and oysters, and sauté them too.
4. Push all the ingredients to one side of the frying pan. Melt the butter in the open space in the pan over low heat. Add the flour and mix it with the butter. Cook the butter-flour mixture well.
5. Add the spinach and mix the ingredients that were pushed to the side back as you sauté everything.
6. Add the milk and soup stock to mix well. Simmer until the sauce has thickened. Adjust the seasoning with salt and pepper.
7. Transfer the contents of the frying pan to a heatproof dish, top with as much cheese as you like, and bake in an oven until the top is browned.
8. You can make this into a rice gratin! Put a small amount of rice in a heatproof dish, and pour the Step 6 mixture over it. Bake as in Step 7. It tastes rich and delicious too!

Story Behind this Recipe

I learned how to simpify the bechamel sauce steps for a gratin in this way a long time ago in a cooking class. Apparently there are many similar methods, but this one is the easiest and is foolproof I think.
