Notes

For more helpful hints, substitution ideas, slow cooking tips, and other delicious recipe ideas, check out my post above.
CROCKPOT COOKING TIPS: Every slow cooker heats a little differently, so cooking times can vary. Once you know how your crock pot runs (hotter or cooler), you can adjust as needed.
TIPS: Steel-cut oats are important for overnight cooking. Do not substitute quick oats, as they will turn mushy. If your slow cooker runs hot, check around the 6½-hour mark. Stir well in the morning before serving.
VARIATIONS: Swap one Granny Smith apple for a Honeycrisp if you prefer a slightly sweeter taste. Add chopped pecans during the last hour for extra texture. For extra richness, stir in a tablespoon of butter before serving. The apples will be very soft after cooking, if you prefer some crunchier apples. Cook only half, then add in the remaining half 1 to 1½ hours before serving.
SERVING SUGGESTIONS: Serve straight from the crockpot and let everyone customize their bowl. This oatmeal reheats beautifully for meal prep breakfasts all week — just warm gently and add a splash of milk to refresh it.
