Have plenty of mashed potatoes or cauliflower mash on hand to soak up every last drop of the gravy, which becomes silky smooth once it thickens in the crock-pot. You're going to want to lick the plate clean!
It's a comforting mid-week dinner. But, because of its beautiful presentation, we also included this crock-pot shoulder roast in our Special Occasion Dinners collection.
There's no rushing around in the kitchen as guests arrive with this dinner. And, the aroma that fills your house is very, very inviting.
Ingredients
Select quality main ingredients to take this slow cooker pot roast over the top.
- Beef Shoulder - We used this boneless cut of meat at our stores. When cooked slowly over low heat, beef shoulders are moist, tender, and easy to slice. Other types you can use include: blade roast, chuck, brisket, or round roasts.
- Mushrooms - Any type of mushroom will work. We used shiitake mushrooms. It's equally delicious with white button, baby Bella, or cremini mushrooms. Or, use a mixture of all your favorites. Be adventurous! The recipe calls for 8 ounces, but mushroom lovers may want to use up to 16 ounces.
- Red wine - Use dry red wine. We used Merlot. Other options include Cabernet Sauvignon or Pinot Noir. Use whatever you like to drink. And, if you don't drink wine, just buy little bottles and store them in a cool place for your next recipe!
- Onion - Roughly chopped white or sweet onion.
- Everything else - You'll also need ketchup, Dijon mustard, Worcestershire sauce, garlic, salt, pepper, and corn starch.
Food allergy tip: Worcestershire sauce contains soy and often gluten. If necessary, leave this ingredient out. We have and still marveled at the result.
Optional: Add potatoes, carrots, and other hearty vegetables. If you do, double the amount of the sauce.

Directions
The preparation of this crock-pot shoulder roast is simple, which is one of the reasons you'll put it on repeat.
1. Brown the Meat
I love beef shoulder roasts because they are relatively low in fat and still cook well in a crock-pot. You do not need to brown the meat on the stovetop first. But you definitely can, and it only adds to the flavor!
To brown the outside of the beef, heat oil (canola, vegetable, or avocado oil) in a large pan over medium-high heat. Pat the shoulder roast dry and add it to the skillet. Cook for about 3 minutes on each side or until browned to your liking.
2. Prepare Mushrooms
Shiitake mushrooms have a smoky flavor and add to the rich flavor of this recipe. No matter what type of mushroom is used, here are a few tips:
- The tough stems should be cut off close to the cap and discarded.
- Mushrooms are very porous, so it's best to wipe off any dirt which a damp paper towel rather than dousing them with water. This is true no matter which type of mushroom you use.
- Slice the mushroom caps into thin slices.
- Use dried shiitake mushrooms after they've been reconstituted.

3. Combine Sauce Ingredients
Mix ketchup, red wine, water, Dijon mustard, Worcestershire sauce, minced garlic, salt, and pepper to make red wine mushroom sauce. That combination may sound odd. But, trust me. It's delicious when it's finished.
4. Add Everything to a Crock-Pot
Place the beef shoulder roast, mushrooms, and onions into the slow cooker and pour the sauce over the top.
We suggest cooking a shoulder pot roast on low for about 6-8 hours for the very best result. However, it can also be cooked on high for about 4-6 hours.

5. Thicken Sauce
The magic occurs at the very end of the cooking process. Lift out the shoulder roast and stir a slushy mixture of corn starch and water into the liquid, mushrooms, and onions. Turn the temperature to high and cook for about 10 minutes more. Keep the meat warm.
The sauce turns into a velvety, delicious gravy that you absolutely have to use on everything in sight.

Freezer Instructions
This was known as Crock-Pot Black Forest Pot Roast at our meal assembly stores. So, it's definitely freezer-friendly before you cook it!
Make an extra bag when shoulder roasts go on sale, and you have everything out.
To make a freezer bag, add all ingredients (except for the slushy corn starch and water mixture) to a large freezer-safe bag. Remove any excess air as you close it. Then, place that bag inside another one as a safety precaution.
This recipe stores well in the freezer for about 2-4 months. Defrost in the refrigerator before cooking as you usually would. Be sure to label it and note that you need to add the corn starch at the end.
FAQ
Pot roast can be tough if cooked too long, not long enough, or if there is not enough liquid in the slow cooker. The proportions and timing for this recipe should yield a fork-tender pot roast with lots of extra sauce. If you add extra ingredients, then double the sauce too.
Add hearty vegetables that can withstand 6-8 hours in a crock-pot, such as carrots. Be mindful of how many extra ingredients you add so there is still enough liquid to keep the shoulder roast moist.
Spoon extra sauce over the pot roast. For small servings, you can cover and microwave for several minutes without it becoming dry. For larger portions, place meat topped with sauce in a covered baking dish and reheat at 300 °F until warmed through, about 20 minutes, depending upon the amount and thickness.
For gravy that is stored separately from the meat, cover and microwave on high for 1 minute. Remove cover, stir and continue heating at 30-second intervals until warmed through.

Lorrie says
Absolutely delicious! Loved the gravy and the meat was tender and flavorful. Thank you!
Tammy Marie Blevins says
I missed the part where you only pat the mushrooms so I didn't cut off the stems and doused them with water. Ugg. Will my roast still turn out ok with my mistake? This is my first time to make this recipe so I can't rate it at the moment. I pray I haven't messed it up.
Thank you for your time.

I think it will turn out just fine! Stems that are hard or woody won't be as pleasing, but they shouldn't hurt anything. Since the mushrooms are being mixed into a sauce, a little extra water shouldn't be a problem either. I hope you enjoy it!
Lucy says
This is the best pot roast I've ever made, and I've used many pot roast recipes over the years! I followed the recipe, with one exception. I used canned sliced mushrooms as that's all I had. This was easy to put together and was really delicious!! Thank you for this recipe! It's definitely a keeper!!
Marjory Pilley says
I'm so glad you enjoyed it!
Angie says
For doubling the sauce arenyou doubling all ingredients other than the roast. I know probably a silly question but wanted to check. Excited to make this!!
Marjory Pilley says
Yes! Double mushrooms and onions too.
Jon says
Hello,
Making this today! When should I add the potatoes and carrots?
Marjory Pilley says
Hi! You can add these at the beginning or even a few hours afterward if you like!
John says
Does it matter if I put the roast on top of the veggies or bottom?
Keith says
First time I didn’t use bullion in the sauce and I used onion salt instead of real onions because of stomach issues, but the sauce was so tasty!
Amber says
When you add the cornstarch slurry to the slow cooker at the end, do you leave it open or cover it with a lid to thicken for the 10 to 15 minutes on high?
Marjory Pilley says
Hi! The cornstarch should thicken it either way. But, I typically leave it off.
John Rhodes says
What can i use instead of the wine
Marjory Pilley says
Try a red grape juice! It should substitute one for one. To make the juice less sweet add a 1/2 teaspoon of vinegar or more to taste, if desired.
