Let’s take a look:
The Process

- Step 1: For a more rustic flavored potato, we’ll oven roast russet potatoes in their skins, rather than peeling, cubing and boiling like we would for mashed potatoes. They’ll have a coarser texture and fuller potato flavor. Rub them with oil, sprinkle with coarse salt and bake until tender. About 1 hour, depending on the size of the potatoes.


- Step 2: Once the potatoes are cooked, let them cool for about 15 minutes. Using a knife, the skins can easily be removed. Place the potato flesh in a large bowl and add softened room temperature goat cheese.
- Step 3: Use a potato masher to blend the goat cheese and potatoes. No need to mash them to a creamy mashed potato consistency. Remember this is a rustic recipe.


- Step 4: Add the salsa, salt and the Sambal Oelek.
- Step 5: Use a potato masher to mix well. Taste and adjust for flavor. Add more Sambal Oelek is you want it spicier.


- Step 6: Use a knife to make a slit in the roasted poblano peppers. Remove the large seed pod at the top and scrape out most of the seeds. Use a spoon to stuff each poblano with a good amount of the potato mixture. Place each stuffed pepper on a sheet pan.
- Step 7: Place a pat of butter on top of each of the mashed potato stuffed poblano peppers.

- Step 7: Bake 350 degrees for 30 minutes. If you’d like them browned, finish them under the broiler for just a minute. Serve in your favorite festive Southwestern dish.

How To Roast Poblano Peppers Stove-top
Place poblano peppers over medium high heat directly on gas stove grates. Use tongs to turn frequently until the skin is blistered. Place the blistered pepper in a plastic bag but don’t seal. Let them steam for about 15 minutes then remove skin. This can also be done on an outdoor grill.
Questions You May Have
Russet potatoes have a high starch content and are better for smashing or mashing. Save those Yukon Golds for frying or for soup recipes like this recipe for Hamburger Potato Soup.
Tips For Success
- Allow one hour for goat cheese to come to room temperature.
- Each Fall, when chile roasters are fired up, buy a good stash of roasted poblano peppers and keep them in the freezer. Much easier than roasting them yourself.

Mashed Potato Stuffed Poblano Peppers
Ingredients
- 4 large Poblano pepers roasted and split in half
- 6 medium Russet Potatoes baked
- ¼ Cup Heavy cream
- 4 ounce Log of Goat Cheese room temperature
- ½ cup Mexican Salsa mild or medium
- 1 Tablespoon Sambal Oelek
- Salt and Pepper to Taste
- 3 Tablespoons Butter divided into 6 chunks
Instructions
- Bake potatoes at 350 degrees until tender.
- Roast poblanos over open flame on your gas stove top. One by one, simply place the poblanos directly on the grates turning them often to get the black and blistered.
- When the poblanos are cool enough to handle, make a slit down the center of each pepper. Remove some of the seeds and a little bit of the veins if you’d like. This will make the peppers less spicy with heat. I don’t remove much of the blackened skin, because this is where the smoky flavor lies. If you must remove skin, do so with your hands. Don’t rinse the peppers under water. You’re rinsing away flavor.
- Once cooked, let the potatoes sit for about 15 minutes, and when cool enough to handle, use a knife to remove the potato peel. The peel will come off easily in big strips. Scrape any large bits of potatoes from the peel. Add the potatoes and cream to a bowl and use a potato masher to mash until somewhat smooth. This is a rustic recipe, so they don't have to be creamy like mashed potatoes.
- Mix in the goat cheese.
- Add the salsa, salt and the Sambal Oelek. Mix well. Taste and adjust for flavor. Add more Sambal Oelek is you want it spicier.
- With a spoon, stuff each poblano with a good amount of the potato mixture. Place each stuffed pepper on a sheet pan. Place a pat of butter on top of the mashed potatoes.
- Bake 350 degrees for 30 minutes. If you’d like them browned, finish them under the broiler for just a minute.
Notes
- Allow one hour for goat cheese to come to room temperature.
- Each Fall, when chile roasters are fired up, buy a good stash of roasted poblano peppers and keep them in the freezer. Much easier than roasting them yourself.
