This oven-baked Chicken stroganoff is one of those cozy, no-fuss dinners that feels a little special without asking much of you. Just four ingredients, one pan, and about an hour — and what comes out is tender chicken in a thick, creamy mushroom sauce with golden, bubbly edges that are almost impossible to resist. It’s the kind of weeknight dinner that makes the whole house smell incredible.
Why You’ll Love It
- Truly four ingredients — nothing fancy, nothing you need to make a special trip for. It’s very likely already in your pantry.
- No browning, no stovetop — the chicken goes in raw and the oven does all the work.
- Rich, creamy sauce — thick and coating, not watery or thin, with lightly golden edges that are the best part.
- Great leftovers — the sauce reheats beautifully and might actually be better the next day.
- Minimal cleanup — one mixing bowl and one baking dish. That’s it.
A Few Notes on the Ingredients
The condensed cream of mushroom soup — don’t add water. You’re not making soup. You’re using it as a sauce base, and it goes in thick, right from the can. I use two cans, which feels like a lot until you spread it over two pounds of chicken and realize it’s exactly right.
The sour cream is what gives this its stroganoff quality — that slight tang that lifts the whole thing. Full-fat. I know, I know. But you’re not eating this every day, and the light version gets a little thin and sad in the oven. I’ve tried it. It works, but just barely.
The dry onion soup mix is the flavor engine of the whole dish, and I say that with full awareness that it’s a packet of dehydrated onions and MSG and whatever else they put in there. It doesn’t matter. It’s delicious. I’ve tried substituting it with actual onions and fresh herbs, and I won’t be doing that again.
The chicken: boneless, skinless breasts, cut into bite-size pieces. I cut mine medium — not too small, or they dry out before the sauce has time to do anything. Thighs also work if your family prefers dark meat, though the cook time can vary a bit, so watch it.
Ingredients
- 2 pounds boneless, skinless chicken breasts, cut into bite-size pieces (I go about an inch and a half)
- 2 cans (10.5 ounces each) condensed cream of mushroom soup — do not add water
- 1 cup sour cream, full-fat if you can manage it
- 1 packet (about an ounce) dry onion soup mix
How to Make It
Preheat your oven to 350°F. Get out your 9×13 glass baking dish — I always use glass for this because I feel like it heats more gently and the sauce doesn’t scorch the way it can in a dark metal pan — and give it a light spray or rub of butter so the edges don’t stick.
Spread your chicken pieces in a single layer across the bottom of the dish. This part matters more than it seems like it should. If you pile the chicken up, the pieces in the middle won’t cook evenly, and you’ll end up with some that are tender and some that are still a little dense. Spread them out. It’s fine if a few overlap a little, but do your best.
In a bowl — medium, doesn’t need to be big — stir together the two cans of soup, the sour cream, and the whole packet of onion mix. Stir until it’s smooth and even, no streaks of sour cream running through it. It’ll be thick. That’s correct. Pour it over the chicken and use a spatula to spread it all the way to the edges so every piece is covered.
Cover the dish tightly with foil. This first part of the baking is gentle — you’re letting the chicken cook through without letting the top dry out. Put it in the center of the oven and leave it for 30 minutes.
After 30 minutes, take off the foil — carefully, there will be steam — and give the sauce a little stir around the edges where it tends to be thicker. Then put it back in, uncovered, for another 20 to 25 minutes. You’re looking for bubbling around the edges, a little bit of golden on the top of the sauce, and chicken that registers 165°F when you stick a thermometer in the thickest piece. I bought a cheap instant-read thermometer years ago and I use it constantly, for this and about a dozen other things.
When it comes out, let it sit for five minutes or so. The sauce tightens up a little as it cools, which is a good thing — it clings better to the Noodles that way.
Serve it over egg noodles, rice, or mashed Potatoes. My personal preference is wide egg noodles with a little butter tossed in while they’re still hot. Add something green — green beans, a salad, roasted asparagus if you’re feeling ambitious. Warm bread if you have it, for the sauce.
Variations
You can swap the cream of mushroom soup for cream of chicken if mushrooms aren’t your thing. It’s good — sweeter, milder — but it tastes like a different dish. Not worse, just different.
If you want a little tang after baking, stir in an extra tablespoon or two of sour cream right before serving. It brightens the whole thing.
For anyone who loves mushrooms, I sometimes do buttered egg noodles with sautéed mushrooms on the side — that way the bake itself stays four ingredients, but mushroom lovers get their fix and it doesn’t complicate the main dish.
If you’re making this for picky eaters or kids, cut the chicken smaller — closer to half an inch — and serve the chicken and sauce separately so they can take just what they want. Less intimidating on the plate.
Storage
Leftovers go in a shallow container in the fridge, and they’re good for three or four days. Reheat on the stovetop with a splash of water if the sauce has thickened too much, or in the microwave covered with a damp paper towel so it doesn’t dry out.
You can also assemble the whole dish the night before and refrigerate it covered — I do this when I know the next day is going to be long. Add about ten extra minutes to the baking time if it’s going in cold.
Final Notes
One thing I never think to mention until after the fact: this is a great dish for when you’re tired. I mean genuinely tired, the kind where you’re staring into the refrigerator at 5:30 wondering how any of this is going to become dinner. Four ingredients, one pan, an hour. That’s all it asks of you. The oven does the rest.
This one’s been in my rotation for a long time, and I don’t see that changing anytime soon.
