Tips, Notes & Q&A

Can I use homemade meatballs?
Absolutely. Homemade meatballs work wonderfully—just brown them first so they hold their shape during the long cooking time.
What potatoes work best?
Baby Yukon Gold or baby red potatoes are ideal because they stay tender without falling apart.
Can I add vegetables?
Yes. Mushrooms, carrots, pearl onions, or green beans are delicious additions that cook well in the slow cooker.
How do I thicken the gravy?
Mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir it into the slow cooker during the final 20 minutes, and cook until the gravy thickens.
Storage & Reheating:
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop or in the microwave. This dish also freezes well for up to 3 months.
