- Keep gravy silky: add slurry slowly to simmering juices; stop when it coats a spoon.
- Salt at the end after reducing; broth brands vary.
- For tidy slices, cook to 190°F and slice thick; for pull-apart, go to 200–205°F.
Variations

- Garlic-Herb Swap thyme for Italian seasoning; add 4 extra cloves garlic.
- Open-Face Melt Top beef with provolone, broil 1–2 minutes until bubbly.
- Veg-Forward Load the pot with carrots and celery for a stew-style roast.

FAQs
What cut works best?
Chuck roast has the right fat and collagen for tender, shreddable meat.
Can I skip searing?
Yes. Searing adds depth, but the slow cooker alone still delivers rich flavor.
How thick should the gravy be?
Coat-a-spoon thick. Start with the listed slurry; add more if you prefer thicker.
Is this gluten-free?
Yes if you use GF Worcestershire and serve on GF toast; cornstarch is GF.
