Witches Brew Stew–a spooky soup for your little ghosts and goblins. An easy ground beef and smoked sausage vegetable soup made in your Instant Pot or Crockpot.

Witches Brew Stew
Today’s recipe is perfect for a Halloween dinner. With mushrooms that look like skulls (it’s not hard, don’t worry) and lots of hearty bites of sausage and potatoes this will be a perfect pre trick-or-treating supper. You can choose to make this soup in your Instant Pot or the Crockpot, both methods work great. This makes quite a bit of soup so you can halve the recipe for a smaller group or save the rest in the freezer for a future dinner.
Ingredients/Substitution Ideas
- Canola oil–or olive oil
- Beef smoked sausage–or kielbasa or andouille sausage
- Lean ground beef–or ground turkey
- Onion–or shallot
- Celery
- Beef broth–or water and Better than Bouillon
- Carrots
- Italian seasoning
- Garlic powder
- Black pepper
- Campbell’s French Onion Soup
- Tomato sauce–or condensed tomato soup
- Russet potatoes–or red potatoes
- Bay leaf
- Mushrooms–white or baby bella
Steps
Turn Instant Pot to saute setting. When display says HOT add in the oil and swirl around. Add in the smoked sausage and brown for about 2 minutes on each side.

Add in the ground beef, onion and celery and brown for about 5 minutes. If there is excess grease drain it off.

Pour in the broth and scrape bottom of pot so that nothing is sticking. Keep the pot on saute so that the broth can start heating up. Add in the remaining ingredients (except the mushrooms).

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 10 minutes on low pressure.

While the soup is cooking make the mushroom “skulls”. Slice the mushrooms in half lengthwise.

Use a skewer to poke out holes for eyes and use a knife to make two slits for a nose. I also made slits on the stem.

Once soup is done cooking release the pressure and add in the mushrooms. Replace the lid and let it sit on warm for about 10 minutes to semi-cook the mushrooms.

Discard the bay leaf. Ladle into bowls and serve with bread or crackers.

Notes/Tips
- Serve with cornbread, garlic bread, french bread or breadsticks.

Very good. I made it last night after getting home from work. Simple ingredients, easy prep (total time from prepping ingredients to serving the soup took me a bit longer than 25 minutes). My husband loved it, he had seconds and said to make another batch before we run out of the leftovers. Our son liked it as well. Only thing I’ll do different next time is half moon cut the sausage. I’ll definitely be trying more recipes from your site. Very helpful when you have kids and work and are burnt out on making dinner.

Thank you so much for the nice review and the 5 stars Saige!
Made this last night and it was super yummy – there wasn’t much leftover at all, that means it’s a definite keeper! Only things I did differently was use tomato puree (on accident, thought I opened a can of sauce, and didn’t want to waste it) and no mushrooms since my guys (son & hubs) don’t like them. I love it when I read one of your recipes and realize I have everything I need to make it! Thank you once again for a fantastic recipe – you are my go-to IP source!

That is such a good feeling! I love not having to go to the store 😉
Agreed!! And an update: Hubs took the leftovers to work and said it was even better! Thanks again for the great recipes!!
