Hearty, juicy and warming casserole is ideal for cool September evenings! So, I suggest to practice. I recommend that you buy a grain-fed beef tenderloin. Yes, she is not so fat, but much more useful.
Slice the mushrooms, onions and peppers. Slightly fry in butter for 2-3 minutes and put in a bowl.
In the same pan, fry the beef for five minutes, add the garlic, salt and pepper. Return the vegetables and fry for another 3-5 minutes, sprinkle with Italian herbs. Put everything in a baking dish, sprinkle with grated cheese and send to a preheated 420 ° F oven for 15 minutes or until the casserole is covered with a golden crust.
Remove from the oven, brush with tomato sauce and lightly pour olive oil.
Bon Appetit
