Oven-roasted tri-tip with green chile-jalapeno mashed potatoes

As you may remember, my friends at Certified Hereford Beef hooked me up with a couple of AMAZING tri-tips earlier this month. The first one I grilled, but for the second one I thought I would show how versatile this cut is by oven-roasting it. After all, sometimes grilling just doesn’t fit the rest of your plan! I also wanted to experiment a little with my mashed potatoes and make something a little Tex Mex-y. Here’s how you can duplicate both.

Oven-roasted tri-tip


1 tri-tip

Coarse sea salt

Coarse black pepper

Garlic powder

2 tablespoons unsalted butter


Pre-heat oven to 350 degrees.

Sprinkle both sides of the meat with the seasonings.

Heat an oven-proof Dutch oven on the stove to medium-high heat.

Add butter to Dutch oven and allow to melt thoroughly.

Add tri-tip and cook 5 minutes per side to sear.

Transfer to oven and cook 25- to 35- minutes or until an instant-read thermometer indicates desired doneness. (I like to pull mine out before it’s quite to the desired temp since it will continue to cook just a little more while it rests.)

Move tri-tip to a plate and tent with foil. Allow to rest about 5 minutes before slicing.

Green chile-jalapeno mashed potatoes


1 baking potato

1 head of garlic (I use most or all of the cloves, but if you don’t love garlic the way we love garlic, just reduce the amount.)

Olive oil

Sea salt

Coarse pepper

¼ cup heavy whipping cream

5 Tbsp. unsalted butter

2 jalapenos, stemmed/seeded and then minced

½  can chopped green chiles

½ cup sharp cheddar cheese (optional)


To the roast the garlic:

Cut the top off and discard, exposing the cloves.

Brush or spray the exposed cloves with olive oil and sprinkle with sea salt and coarse pepper. Wrap in foil and roast in a 350 degree oven for 30-45 minutes. (You can do this up to several days ahead of time and refrigerate it, or do right before you need it.)

When you’re ready to cook the potatoes (about 40 minutes before you’re ready to eat dinner):

Wash and cut the potato into 4 pieces. (You can peel it if you want, but I prefer skin-on.)

Place the potato pieces in a pot and cover with water. Squeeze the garlic cloves into the pot. Bring to a boil on stove and cook until tender, about 35 minutes or so usually.

While the potatoes are cooking, add the heavy whipping cream and butter to a saucepan and heat on medium. Allow to reduce. The process only takes about 10-15 minutes, but it won’t hurt to start it when you start the potatoes and just reduce the heat or even turn it off toward the end.

When potatoes are done, drain and pour back into pot or into a mixing bowl. (I like to use my stand mixer if it’s not already in use.) Add the butter and cream mixture a little at a time (you probably won’t need it all, especially if you’re like me and like your mashed potatoes a little on the dryer side), add the peppers and cheese in, and mix using an electric mixer until you’ve reached your preferred consistency. Add some sea salt and coarse pepper and give it another quick mix.
Our dinner looked like this:


  1. These recipes both sound yummy! Tri-tip is a favorite in these parts of the country, but I've only had it on the barbeque. Will have to try this oven version!

  2. This looks incredible! I can't wait to try it, myself!
