# Additional Tips::

01 -
  • The slow cooker does all the heavy lifting while you live your day, and somehow that feels like cheating in the best way.
  • That packet of onion soup mix is basically liquid gold in beef form—it builds layers of flavor you'd normally fuss over for hours.
  • Vegetables become silky and sweet, the meat falls apart at a whisper, and the gravy tastes like someone actually knew what they were doing.
02 -
  • Do not, under any circumstances, turn the heat up to HIGH thinking you'll save time—the low steady heat is what transforms tough meat into velvet, and rushing ruins the entire point.
  • Some onion soup mixes contain gluten hiding in the thickeners and seasonings, so read your packet carefully if anyone eating has a sensitivity.
03 -
  • If you want even deeper flavor, sear the roast in a hot skillet with a little oil before it ever sees the slow cooker—those brown bits matter more than you'd think.
  • The optional cornstarch thickener should be mixed with cold water first, or it'll clump into unpleasant granules in your gravy.
