Chef Tips from the Video

  • Use a meat thermometer for precise roast cooking.
  • Add a small sprig of fresh thyme to the sauce for extra aromatic depth.
  • For ultra‑creamy mash, incorporate the butter before the milk.

Troubleshooting

The roast is too dry.

Check the internal temperature; reduce cooking time or add a splash of broth during cooking.

The sauce forms lumps.

Dilute the cornstarch in cold water before adding, then whisk vigorously.

The spinach remains too watery.

Cook uncovered for a few extra minutes to evaporate excess liquid.

The mash is too watery.

Add a bit more butter or let rest for 2 minutes to thicken, or mash further.

Storage

Refrigerator: Sauce, leftover roast, mash and spinach keep for 3 days in the refrigerator.

Freezer: Roast slices and sauce can be frozen for 2 months. The mash freezes for 1 month.

Room temperature: Do not leave at room temperature for more than 2 hours.

Make-Ahead Tips

  • The roast can be seared ahead of time and finished in the oven just before serving.
  • The sauce stores well; prepare it the day before and gently reheat.
  • The mash can be kept warm in a bain‑marie.
  • Creamed spinach reheats quickly over low heat.
