The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

3 to 3½ pounds caramelized succulent protein, such as a boneless roast or similar slow-cooking cut – For tender, flavorful protein.
1 large yellow onion, sliced – For sweetness and depth.
1 cup barbecue sauce – For tang, smoke, and sweetness.
½ cup apple cider or apple juice – For a warm, fall-flavored sweetness.
1 teaspoon smoked paprika – For smoky color and depth.

Step-by-Step Instructions

Step 1: Layer the Onions

Scatter the sliced onion across the bottom of the slow cooker to create a bed for the protein.

Pro Tip: The onions act as a natural rack, keeping the protein from sitting in the juices and becoming soggy.

Step 2: Add the Protein

Place the protein on top of the onions. In a small bowl, stir together the barbecue sauce, apple cider, and smoked paprika, then pour the mixture over the top.

Pro Tip: Pour the sauce slowly and evenly so it covers as much of the protein as possible.

Step 3: Cook Low and Slow

Cover and cook on low for 7 to 8 hours or on high for 4 to 5 hours, until the protein is very tender.

Pro Tip: Don’t lift the lid! Every time you open the slow cooker, you lose heat and add cooking time.

Step 4: Rest and Serve

Carefully transfer the protein to a platter or shred it directly in the cooker if that suits the cut. Spoon some of the onions and sauce over the top, then let it rest for 5 minutes before serving.

Pro Tip: Serve with mashed potatoes, rice, or crusty bread to soak up every drop of that delicious sauce.

How to Serve It Like a Pro

This Trick-or-Treat Warm Up is delicious on its own, but a few simple sides make it a complete meal:

Pro Tips for the Best Trick-or-Treat Warm Up

Layer the onions first. They act as a rack for the protein.
Pour the sauce slowly. Covers the protein evenly.
Don’t lift the lid. Keep that heat and moisture inside.
Cook low and slow. The low temperature makes the protein tender.
Check for doneness. The protein should fall apart at the touch of a fork.
Shred or slice the protein. Both work beautifully.
Spoon the sauce over the top. Every bite should be coated.
Serve with a starch. Mashed potatoes, rice, or bread soak up the sauce.
Make extra. It disappears fast!
Store properly. Keep in an airtight container in the fridge.

Frequently Asked Questions

Can I use a different type of protein?
Yes. Beef chuck roast, pork shoulder, chicken thighs, venison, or turkey breast all work beautifully.

Can I use frozen protein?
Yes, but you’ll need to add 2-3 hours to the cooking time. Make sure the protein reaches a safe internal temperature.

Can I use a different type of sauce?
Yes. Honey BBQ, spicy BBQ, Carolina Gold, Kansas City Style, or maple BBQ all work beautifully.

Can I use apple juice instead of apple cider?
