Crockpot Tri-Tip and Mash

Crockpot tri-tip and mash in a white bowl on a countertop

Last updated on January 17th, 2026

I love using my crockpot because, it means…I get to chill out! Toss it in there and forget about it! This Crockpot Tri-Tip and Mash was so delicious and SO easy! Of course, I used an amazing Tri-Tip Steak from Snake River Farms! Their meat is just unbelievable! It’s perfect, not a single fatty gross bit, nothing. I loaded this roast up with a bunch of fresh herbs, spices and let the crockpot do the rest. The smell of the house, wow. Wish I could make an air freshener out of it!

In a cast iron skillet melt the butter needed for tri-tip on medium-high heat. Sear the roast on one side, for a few minutes, then flip and cook a few minutes more.

To cook in the crockpot:

Transfer tri-tip to the crockpot and dump in that butter and bits from the skillet. Lay garlic over the tri-tip and dump in the beef broth.

Cook for 6-8 hours on low, start checking after 6. Mine was done right at 6, but all crockpots are different!

When roast is tender enough to pull apart with a fork, remove from crockpot and shred with two forks. Pour in heavy cream and cook on high for 30 minutes more. While that’s cooking let’s get our mushrooms and potatoes ready.

To make potatoes:

In a large pot, boil potatoes for about 15 minutes, until fork tender. Remove from pot, drain, and move pot to a solid surface for mashing. I like to lay some hot pads down on my counter and do it there. Mash potatoes well, peels and all, I like to leave mine a little chunky! Add in all other potato ingredients, stir until combined completely. Set aside until ready to use.

To make the mushrooms:

In my experience, mushrooms are hit or miss in the crockpot because of the moisture, so I chose to sauté them quick. In a small saucepan on medium heat, melt the butter for the mushrooms. Add mushrooms and Lawry’s to the pan and cook until mushrooms are tender and have a sort of golden crisp to them, about 5 minutes.

To serve crockpot tri-tip and mash:

Scoop some mashed potatoes into a bowl, layer on that beautiful Tri-Tip and juice over the top and finally top off the Crockpot Tri-Tip and Mash with the mushrooms and some fresh parsley! Enjoy!
