[Leftover] Pot Roast Stuffed Portobellos
with mixed greens salad

Active: 40 Total: 40

To build flavor in Monday's leftover pot roast, saute it with onions before using it as a filling for tender roasted portobello mushrooms. This meal was last featured in 2021.
Smarts: The au jus used for topping should be quite thin, but adding a bit of arrowroot powder helps it to thicken slightly.

Make

  1. Heat oven to 425F / 218C.

  2. Place mushrooms on a sheet pan. Brush mushrooms on both sides with some oil. Transfer pan to oven and roast until mushrooms are starting to soften, 8 to 10 minutes.

  3. Remove pan from oven and season mushrooms generously with some salt and pepper. Return mushrooms to oven and continue roasting until very tender, 5 to 10 minutes more (depending on size / thickness).

  4. While mushrooms roast, melt butter in a skillet or saute pan over medium heat. To melted butter, add onions with some salt. Saute until onions are translucent and very tender, 5 to 6 minutes. Add leftover pot roast and saute until heated through, 4 to 5 minutes more. Set meat / onions aside and return pan to heat.

  5. To heated pan, slowly add cooking liquid, scraping up any browned bits on the bottom of the pan. Whisk together aminos and arrowroot powder. When cooking liquid is simmering, whisk in aminos mixture and cook until slightly thickened, 1 to 3 minutes. Set aside.

  6. Just before serving, toss greens with vinaigrette, sunflower seeds, and avocado.

  7. Fill mushroom caps with meat and onions. Drizzle with au jus. Enjoy salad on the side.
