First, cut the meat into thick pieces

I'm going to bake it a little wider, but I'll cut it in the middle

I marinated it with salt, pepper, olive oil and rosemary

First, cook it in the pan, back and forth

I put it on the oven pan and grilled it again with garlic

Add butter and flour in equal amounts, stir-fry flour so that it doesn't burn, pour milk slowly, mix until thickened, and season with salt and pepper to complete the white sauce

Blanch the mushrooms in water.. Boil it in the pre-made bechamel sauce, and the mushroom cream sauce is done

Put the grilled garlic and vegetables on top of the steak

Sprinkle the pre-made mushroom sauce

It's done
