What To Serve With This Dish

While this Instant Pot frozen beef roast can be served as a meal on its own, I like to pair it with a light side dish, such as green bean salad, or a hearty bread like this cheddar jalapeno bread. However, the options are endless, so add what your family enjoys.

Substitutions and Additions

  • Swap the vinegar: Use balsamic vinegar instead of red wine vinegar for a richer flavor.
  • Sweet potatoes: Swap sweet potatoes for regular ones for a sweeter twist.
  • Veggie boost: Add celery or sliced zucchini with the carrots for more veggie goodness.

How To Store

  • Storage: Keep leftovers in an airtight container in the fridge for up to 4 days.
  • Freezing: Freeze in portions with some broth in airtight containers for up to 3 months.
  • Reheating: Reheat gently on the stove or in the microwave with a splash of broth.

Sandra’s Pro Tips

  • Rest time: Let the roast rest a few minutes before slicing so it stays juicy.
  • Want thicker broth? Mix a little cornstarch and water and simmer it down after cooking.
  • Release slowly: Don’t skip the natural release! It’s key to keeping the meat tender.
