Onions baked with rosemary and cream is a luxurious yet simple side dish that transforms humble onions into something rich, savory, and deeply flavorful. Slow-baked until tender and caramelized, the onions develop a natural sweetness that pairs beautifully with the earthy aroma of rosemary and the indulgent richness of cream.
This dish starts with sweet or yellow onions, peeled and halved or thickly sliced. As they bake, the onions soften, mellowing in flavor and taking on a buttery texture. The addition of fresh rosemary infuses the dish with a fragrant, herbaceous note that perfectly complements the sweetness of the onions.
Heavy cream is poured over the onions before baking, creating a luscious sauce that thickens as it cooks. The cream absorbs the flavor of the onions and rosemary, turning golden and slightly bubbly around the edges. Some variations add a sprinkle of Parmesan or Gruyère on top for an extra layer of savory richness and a beautifully browned, crisp finish.
Onions baked with rosemary and cream is a versatile side dish that fits seamlessly into both holiday feasts and everyday meals. It pairs especially well with roasted meats like turkey, chicken, pork, or beef, offering a creamy contrast to crispy, roasted textures. It also complements vegetarian mains, lending depth and richness to the plate.
Despite its simplicity, this dish feels elegant and comforting — the kind of side that guests rave about and request again. It brings warmth and rustic charm to the table, with the bonus of filling the kitchen with the inviting aroma of rosemary and caramelizing onions.
For drinks, it pairs wonderfully with white wines like Chardonnay or Viognier, a dry cider, or even a crisp sparkling water with lemon.

I dunno, I followed the recipe but my onions turned out all mushy. Maybe I left them in too long? Not sure if I’d try it again.
Mushy onions can happen if they bake too long or at too high a temp. Maybe try checking them earlier next time!
Why cover with foil? I never understand that part. I usually cover my food with a lid instead. Just an idea, heading off to the store to grab onions!
Why would you put cream on onions?? Seems like a waste of good onions to me.
Onions? Really? I thought this was gonna be a stew or something! But I can’t believe how good these taste! I might even bake my socks now just to try more flavors! 😂
I never thought onions could taste so good! Your comment made me laugh 😊. Going to try this for sure!
This recipe is just amazing! The flavor of the rosemary with the creamy onions is like heaven. I made it for a dinner party and everyone loved it! 😍
Is 350°F really enough? I bake at like 400°F. Seems like it’d take forever to cook.
I’ve always baked onions at 350°F and they come out great! It’s not about the temperature, but the time. Just give it a shot! 😊
I dunno man, 350°F seems kinda low. What if they just turn mushy? I prefer higher temps for better browning.
This was super easy to make and tasted heavenly! ⭐⭐⭐⭐⭐
This dish is absolutely delicious! The rosemary gives it such a nice flavor. My family loved it.
I totally agree! The rosemary really takes it to a whole new level. It’s my go-to recipe now! 😋
Sounds good, but I’m not sure about the cream. I feel like it might be too rich. Anyone tried it without??
I tried this with 5 onions, half cream and half yogurt, tasted interesting. I think I liked it better that way!
Onion dish? Nah, I prefer my veggies steamed or raw. Pass.
You gotta try this! Baked onions are so good with that cream and rosemary. Trust me, they’re better than raw! 😋
Baked onions? Sounds weird, but I gave it a shot. They came out soft but I couldn’t taste the rosemary much. A little bland.
Simple yet delicious! I paired it with grilled chicken and wow!
First time trying this and it was sooooo oily! Maybe I added too much oil? 🤔
Onions? Really? No thanks. 😒
Onions are great! They add so much flavor. You might want to give it a try! 😊
Like, how do you even bake onions? Just boil em, right? Confused.
This recipe is great! The cream really makes the onions melt in your mouth! 👌🏼⭐️⭐️⭐️⭐️⭐️
Easy to make and tastes great! The rosemary really adds a nice touch.
Can I use olive oil from the store? I got some really cheap one. 🌿
Sure, but be careful! Cheap oils can change the flavor. Maybe try a little taste first? 👀
I dunno, is that really a good idea? Olive oil is kinda important for the taste. Just sayin’.
I substituted almond milk for the cream and it was still good! 😋
WOW! Just wow!! Who knew onions could taste this good! Definitely making again!
I don’t even like rosemary, but this recipe changed my mind!
LOVE this! Super easy and impressive for guests! Perfect for dinner parties! 🌟
I tried this recipe and it was a hit! Everyone loved it. Definitely impressed my guests! 🎉
Onions should never be baked! Just grill them! ⭐
This was amazing! The flavors were so rich and creamy. My family loved it!
Gonna pass on this one. Baked onions don’t sound appealing to me at all.
I can see how baked onions might sound weird. But they taste so good once cooked! Give it a try, you might be surprised!
These onions tasted weird. I don’t get why people like them so much. 1 star!
I tried it but found it a bit too creamy for my taste. Might reduce the cream next time.
Just okay. Needs more seasoning or something. Not bad but not great either.
Why use cream? Onions are good enough on their own. #healthyliving
I made this for dinner and it was gone in minutes! So creamy and flavorful!
Yumm! Perfect side for steak. Definitely a keeper! 🥩✨
Not sure about that… Creamy onions? Sounds a bit weird to me. 🤔
Absolutely agree! These onions make everything better. It’s a win-win! 😍
I used green onions instead and it didn’t turn out the same. Should’ve stuck with regular! Lesson learned.
Onions? Yuck! You can keep your fancy recipes. No thanks!
I think I added too much salt. Next time, I’ll be more careful. But still good!
Better too much salt than too little! Glad it still turned out good. Next time, just take it easy with the shaker!
Too much salt? That’s a bummer. I always think it’s those little things that ruin a dish. Maybe just be more careful next time, or try measuring it out?
Pretty good! I used thyme instead of rosemary, and it came out nice, too! ⭐⭐⭐⭐
Sounds good! I’ve also tried it with garlic instead of rosemary, and it was great too. Can’t go wrong with onions! 🤤
Thyme? Really? I’m not sure that would taste the same as rosemary… But hey, if you liked it, good for you!
How long do I bake it for if I’m using smaller onions? 🤔
Not a big fan of the texture of baked onions. Thought it would be different.
This is such a simple yet elegant dish! Loved the flavor! 🌟
I’m glad you enjoyed it! It’s such a delicious way to elevate simple onions. 😋
I tried making this, but the onions came out kinda mushy. Still edible though.
I followed the recipe but forgot to cover it. Oops! Still tasted good but less creamy. Would try again!
Can I use dried rosemary instead? Fresh is so hard to find! Anyway, the recipe looks good.
Instructions were too long 😩 but I guess it turned out fine.
Yummy! But my fam was like, why onions?? ! Haha! ⭐⭐⭐
Haha, yeah, I get it! Not everyone likes onions, but you could totally leave them out if you want. Just saying! 😜
Onions can be a bit weird for some people, but they do add a nice flavor! It’s all about taste. I love it! 🌟
I made this last night and my family couldn’t get enough! Rosemary really makes a difference.
Is this even healthy? So much cream! Why not just boil the onions? 🤔
I’m not really a fan of onions but this recipe is kinda good. Cream makes it better, I think.
I usually hate onions too, but this sounds delicious! The cream really does make everything better. I’m definitely gonna try this.
This was incredible! So creamy and tasty! I never thought onions could taste this good!
Totally agree! I was shocked at how delicious it was too. Who knew onions could be like this? Yum!
Made these for a potluck, and everyone loved them! Easy and fancy!
I dunno, baked onions? Sounds a bit weird to me. But who knows!
Wow, this looks delicious! 🧅❤️ Can’t wait to try it!
I think I forget to cover with foil. They burned on top. 😩
I don’t understand how anyone would want to eat onions like this. 🤢
