Warm, creamy, and weeknight-friendly, this pork tenderloin stew combines browned pork, red potatoes, vegetables, mushrooms, tarragon, and a tangy sour cream finish in one comforting Dutch oven meal.
This is the kind of dinner to make when you want something hearty without committing to an all-day stew. Pork tenderloin cooks relatively quickly, while potatoes, carrots, celery, and mushrooms give the pot enough substance to feel like a complete meal.
The flavor is especially good because the pork is browned first instead of simply simmered in broth. Those browned edges bring extra savory depth, while cider vinegar, a small amount of sugar, and dried tarragon balance the creamy sauce without making it heavy.
The finishing method also keeps the texture dependable. A simple milk-and-flour mixture thickens the broth before sour cream is stirred in over gentle heat, creating a smooth, velvety consistency that coats the pork and vegetables rather than turning the stew overly thick.
Ingredients
- Pork tenderloin: Two pounds cut into roughly 1-inch chunks gives you lean, tender pieces that brown quickly and reheat well in the finished stew.
- Red potatoes: Two pounds of diced potatoes add heartiness while holding their shape better than very starchy varieties.
- Carrots: One cup of sliced carrots brings mild sweetness and color to the pot.
- Celery: One cup adds a familiar savory vegetable flavor to the broth.
- Fresh mushrooms: Eight ounces of sliced mushrooms contribute a deeper, earthy note and make the stew feel more substantial.
- Onion: One medium chopped onion forms the aromatic base after the pork has been browned.
- Garlic: One finely minced clove adds savory depth without overpowering the tarragon.
- Lower-sodium chicken broth: Four cups provide the main cooking liquid and allow you to control the final salt level.
- Apple cider vinegar: Two tablespoons brighten the broth and balance the creamy ingredients added later.
- Granulated sugar: Two teaspoons soften the sharper edge of the vinegar and round out the sauce.
- Dried tarragon: One and a half teaspoons provide the stew’s distinctive gently herbal flavor.
- Olive oil: One tablespoon helps the pork develop a nicely browned exterior.
- Salt: One teaspoon seasons the broth, vegetables, and pork as they cook.
- All-purpose flour and milk: Two tablespoons of flour whisked with ½ cup fat-free milk create a smooth thickener for the broth.
- Sour cream: A ½ cup stirred in at the end adds richness, light tanginess, and the creamy finish.
- Fresh parsley and black pepper: Optional finishing touches that add freshness and a little extra bite at the table.
Cooking Steps
STEP 1: Heat the olive oil in a Dutch oven over medium heat. Brown the pork tenderloin chunks in batches so the pan stays hot and the meat develops color instead of steaming. Transfer the browned pieces to a plate and keep them nearby.
STEP 2: Add the chopped onion to the same pot and cook for about 3 minutes, stirring occasionally and scraping up any flavorful browned bits. Add the minced garlic and cook for about 1 minute more, just until fragrant.
STEP 3: Pour in the chicken broth and add the diced red potatoes, carrots, celery, and sliced mushrooms. Stir in the cider vinegar, sugar, dried tarragon, and salt, making sure everything is evenly distributed through the broth.
STEP 4: Bring the pot to a boil, then immediately reduce the heat to a steady simmer. Cover and cook for 25 to 30 minutes, or until the potatoes and carrots are fork-tender without becoming mushy.
STEP 5: Whisk the flour and milk together in a small bowl until completely smooth. Slowly stream this mixture into the simmering broth while stirring. Let the stew cook gently for about 2 minutes, stirring frequently, until the liquid becomes noticeably thicker.
STEP 6: Return the browned pork and any juices from the plate to the Dutch oven. Heat until the pork is cooked through and hot in the center, then lower the temperature and gently stir in the sour cream. Keep the stew below a boil once the sour cream has been added. Taste before serving and finish with parsley and freshly ground black pepper if desired.
Keeping Leftovers Fresh
Let leftover stew cool before transferring it to shallow airtight containers. Refrigerate it promptly and use it within 3 to 4 days.
For reheating, a saucepan over low to medium-low heat is the gentlest option. Stir periodically and add a small splash of broth or milk if the sauce has thickened substantially in the refrigerator. Avoid bringing it to a hard boil because high heat can cause the sour cream sauce to separate and may also make the lean pork tougher.
The finished stew can be frozen, although dairy-based sauces sometimes develop a slightly grainy texture after thawing. If you are deliberately preparing the dish for the freezer, the smoothest results come from freezing the cooked stew base before adding the sour cream. Thaw overnight in the refrigerator, reheat gently, and stir in the sour cream shortly before serving.
How do I keep the sour cream from curdling?
Turn the heat down before adding it and stir the sour cream into the hot stew gradually. The stew should be hot but not rapidly boiling. Continuing to boil a sour cream sauce after it has been incorporated increases the chance that the dairy will separate.
Helpful Tips
- Brown in batches. Crowding two pounds of pork into the Dutch oven at once traps steam, so working in smaller batches gives the pieces much better color.
- Whisk the thickener thoroughly. Combine the milk and flour until no visible lumps remain before adding it to the pot, then stir continuously as it goes into the broth.
- Watch the potatoes near the end. Red potatoes hold together well, but once they are completely tender, prolonged simmering can cause their edges to break down and thicken the stew more than intended.
Perfect Pairings
A loaf of crusty bread or warm dinner rolls is especially useful for soaking up the creamy tarragon broth and turns a bowl of stew into an even more satisfying dinner.
A simple green salad makes a fresh contrast to the potatoes and sour cream sauce. Keep the dressing relatively light and tangy so it complements rather than competes with the stew.
For a vegetable side, try roasted green beans or broccoli. Their lightly browned flavor works well beside the mushrooms, pork, and creamy broth without adding another heavy element to the meal.
Can I prepare this stew ahead of time?
Yes. You can make it a day ahead and refrigerate it once cooled. Because pork tenderloin is lean, reheat the stew gently rather than simmering it aggressively. If you are planning specifically for make-ahead cooking, you can also wait to stir in the sour cream until reheating.
Can I use another type of potato?
Yes, although red potatoes are particularly well suited to this dish because their waxier texture helps the pieces stay intact as the vegetables simmer. Yukon Gold potatoes are another good choice. Very starchy potatoes can work, but they may break apart more easily and make the broth thicker.
Why are vinegar and sugar added to a creamy stew?
They create balance rather than making the stew noticeably sweet or sour. The cider vinegar cuts through the richness of the sour cream and pork, while the small amount of sugar softens the vinegar’s sharpness. Together they give the creamy broth a more rounded flavor.
Can I leave out the mushrooms?
Yes. The mushrooms add earthy flavor and additional texture, but the cooking method does not depend on them. If you omit them, keep the remaining broth and vegetable quantities the same and check the seasoning near the end, since the overall flavor will be slightly lighter.
The combination of browned tenderloin, tender red potatoes, vegetables, tarragon, and gently thickened broth makes this an especially practical cold-weather dinner. By keeping the pork out of the long vegetable simmer and adding the sour cream only at the end, you get tender meat and a smooth sauce without complicated techniques. Serve it straight from the Dutch oven with bread or a fresh side, and you have a comforting one-pot meal that works just as well for a relaxed family dinner as it does for planned leftovers.

Instructions
- Warm 1 tablespoon olive oil in a medium Dutch oven set over medium heat.
- Add the 2 pounds of cubed pork tenderloin in batches. Cook until the pieces are browned and no longer pink on the exterior.
- Transfer the cooked pork from the Dutch oven and keep it warm while preparing the remaining components.
- Place the chopped medium onion into the same Dutch oven. Cook over medium heat for approximately 3 minutes, or until the onion reaches a crisp-tender consistency.
- Stir in the minced garlic clove and continue cooking for 1 additional minute, stirring frequently so the garlic does not burn.
- Pour in the 4 cups of reduced-sodium chicken broth, then add the 2 pounds diced red potatoes, 1 cup sliced carrots, 1 cup sliced celery, and 8 ounces sliced fresh mushrooms.
- Mix in the 2 tablespoons cider vinegar, 2 teaspoons sugar, 1½ teaspoons dried tarragon, and 1 teaspoon salt.
- Bring the contents of the Dutch oven to a boil. Lower the heat, cover the pot, and simmer for 25–30 minutes, or until the vegetables are tender.
- In a small bowl, whisk together the 2 tablespoons all-purpose flour and ½ cup fat-free milk until completely smooth.
- Slowly pour the flour-and-milk mixture into the simmering vegetables while stirring continuously.
- Return the stew to a gentle boil and cook for approximately 2 minutes, stirring throughout, until the broth has thickened.
- Return the reserved browned pork to the Dutch oven and continue heating until the meat is thoroughly warmed.
- Lower the heat and gently blend in the ½ cup sour cream.
- Once the sour cream has been incorporated, keep the stew below a boil to help prevent the creamy mixture from curdling.
- Serve the pork tenderloin stew hot. Finish each portion with chopped fresh parsley and freshly cracked black pepper, if desired.
Notes
- Whisking continuously while incorporating the flour-and-milk mixture helps produce a smooth consistency and reduces the likelihood of lumps.
- Avoid boiling the stew after adding the sour cream, as excessive heat may cause the dairy to separate.
- A generous scattering of fresh parsley may be added immediately before serving for additional color and freshness.
