Hi there, Ameera here!
We are a sauerkraut loving family. This dish was a home-run for us, and we absolutely loved it. I must state for the record that if you do not LOVE sauerkraut, then you probably won’t enjoy this dish as that is a prominent flavor in this casserole.
We are looking forward to making this dish to celebrate New Year’s Day. In Ohio, we typically make a pork/kielbasa sauerkraut dish with (mashed) potatoes for New Year’s Day. So we decided to flip the script and create something with a similar essence but using a Whole Food Plant Based twist.
This recipe is not a replica of the traditional pork/kielbasa sauerkraut dish, but a whole new dish that is sure to make you forget about the original. We loved this recipe so much; it’s perfect not just for the holiday, but any day of the year.
We hope you give this tasty dish a try!
Tips for Success:
- Flavor Profile: If you do not love sauerkraut, then this recipe may not be for you. The flavor profile highlights the tang of sauerkraut. It basically features a creamy, tangy, slightly smoky sauerkraut flavored sauce mixed with chunky potatoes and mushrooms. The apple pretty much melts into the sauce, and you don’t even taste it, but it very slightly tones down the sauerkraut with a very hint of tiny sweetness.
- Potatoes: We used a 3 lb. bag of B-Size Graded (small-sized) red skinned potatoes, peeled and quartered. You can use your favorite potato in this recipe.
- Oven-Safe Skillet with a Tight-Fitting Lid or Casserole Dish: We used a deep, large, ceramic-lined Dutch Oven style skillet (featured in the photos). If you have a Dutch Oven with a tight-fitting lid, that will work equally well. Dutch ovens are heavy and conduct heat really well by trapping the heat inside. If you need to use a casserole dish, we strongly suggest parboiling the potatoes and covering tightly with heavy duty foil to trap the heat. See notes on Parboiling the potatoes. Make sure the foil does not touch the food.
- Parboiling Potatoes: If you do not have a Dutch Oven or simply want to cut back on oven time, we suggest parboiling the potatoes for 10 to 12 minutes, timing is largely dependent upon the size of the diced potatoes, then adding to the sauce in Step 7. If you use a Dutch Oven, you do not need to parboil the potatoes, they can go directly into the sauce (raw). They will need to be in the oven 60 to 70 minutes due to the thickness of the sauce. If you parboil, then you can reduce the oven time to 30 minutes.
- Additionally, if you plan to parboil the potatoes, do not cook them until tender. You want them cooked about ½ towards being tender. If you accidentally cook to tender, they will fall apart in the sauce.
- If you do accidentally boil the potatoes to tender, do not add them to the Sauerkraut Sauce Mixture. Bake the sauerkraut mixture in the oven without the potatoes for 25 minutes, then gently stir in the tender potatoes to thoroughly coat, then return to the oven for another 7 minutes.
- Sauerkraut: We used a canned sauerkraut, SnowFloss Kraut (plain). It had very little liquid, so we did not drain it. If you are purchasing (or using homemade) sauerkraut that appears to have a lot of liquid, then drain off the water.
- Cashews: The cashews go directly into the liquid mixture to simmer on the stove top as this entire mixture (minus the mushrooms/tamari) will become blended in a high-speed blender.
- Cashew Substitutions: You can try the traditional substitutions: silken tofu, white beans, other nuts or seeds with the understanding that the flavor and texture will change accordingly, and you may need to add ingredients, etc. We have not tested any substitutions.
- Apple: Use a sweet apple like a gala or fuji. You will not taste the apple. It helps temper the sauerkraut just a tiny bit and slightly thicken the sauce.
- Mushrooms: Feel free to use your favorite mushroom in this dish.
- Caraway Seeds: We used ground caraway seeds. This adds great flavor. You can leave it out, but you may need to add some additional spices/herbs to compensate.
- Ume Plum Vinegar: The ume plum vinegar adds depth of flavor. We do not recommend leaving it out. We have no substitutions to offer. If you do decide to leave it out, you may find you need to add ingredients to compensate.
- Sea Salt: Our family was totally divided over the salt. Some members wanted more salt while others felt the sauerkraut was salty enough to season this dish. Please adjust the sea salt based upon your family’s sea salt preferences and/or based upon dietary needs.
- Instant Pot: This dish will not work in an Instant Pot.
Leftovers and Freezing:
Leftovers will generally keep for 4-5 days in the refrigerator. Store in a covered container.
This dish can be frozen.
Pantry Products Used:
- Vegetable Stock: We use Pacific Organic Low Sodium Vegetable Stock. We love this brand because it is Whole Food Plant Based compliant, as it does not contain MSG, has no oil, and does not contain any highly-processed ingredients. Feel free to use your favorite vegetable broth.
- Sauerkraut: We used a 14 oz. can of SnowFloss Kraut (sauerkraut). Feel free to use your favorite brand of sauerkraut or homemade. Watch the ingredients list on store purchased sauerkraut. SnowFloss Kraut (plain) is WFPB, its ingredients list is cabbage, water, salt.
- Ume Plum Vinegar: We used Eden Ume Plum Vinegar. We get a lot of questions on ume plum vinegar. It is fairly inexpensive and adds amazing flavor. You can find it in most health food grocery stores.
- Tamari: We used San J Tamari Soy Sauce, Gluten Free, Reduced Sodium. You can substitute the tamari with reduced sodium soy sauce, Braggs Liquid Aminos, or Braggs Coconut Liquid Aminos.
- Sea Salt: Please adjust the sea salt based upon your family’s sea salt preferences and/or based upon dietary needs.
