Instructions

Creamy gratin

  1. Preheat the oven to 350ยฐF (175ยฐC).
  2. Peel and slice the root vegetables thinly. Heat the heavy cream in a saucepan, press in the garlic. Season with salt and pepper.
  3. Lower the heat and add the root vegetables. Let simmer for 10 minutes on medium-high heat. Stir in the shredded parmesan, saving a small amount of topping. Distribute the gratin into a baking dish or individual ramekins. Top with the remaining parmesan cheese.
  4. Bake in the oven for 20 minutes while you prepare the meat and the butter. You can also prepare the gratin the day before and heat it up before serving. Raise the heat or turn on the grill function towards the end for a nice golden result.

Tarragon butter

  1. Melt one-third of the butter on medium heat until it turns amber in color and smells nutty. Set aside and allow to cool slightly.
  2. Add tarragon, vinegar, onion powder, salt, and pepper.
  3. Whisk the remaining butter into the melted butter and keep whipping with a hand mixer until fluffy.
  4. Keep in the refrigerator but bring to room temperature 15 minutes before serving.

Beef sirloin

  1. Pat the meat dry with a kitchen towel. Rub with salt and pepper on both sides.
  2. Put in a greased oven dish. Insert a meat thermometer in the thickest part. Roast in the middle of the oven until the inner temperature reaches 130ยฐF (54ยฐC), which takes about 30 minutes.
  3. Remove from the oven and allow rest for a few minutes. Cut into slices. Serve with leafy greens, some tarragon butter, and creamy gratin.

Individual steaks

If you choose to use individually portioned steaks, sear them first in a hot pan with butter. 2-3 minutes per side. Then finish in the oven 400ยฐF (200ยฐC) for a few minutes until meat reaches your desired temperature.

    We loved the steak and tarragon butter. My kids and husband didn't like the creamy gratin I thought it was enjoyable.

    is there a substitute for turnip? I'm not a fan

    You could try radishes or rutabaga.
