Oh my goodness, let me tell you about my new obsession, Lemon Cream Onion Boil! It’s one of those magical dishes that looks fancy but couldn’t be simpler to make. I first tried this at a friend’s backyard barbecue last summer, and let me tell you, I’ve been making it weekly ever since. Sweet onions turn into these tender, buttery vessels that just melt in your mouth, with that bright lemon cream adding the perfect tangy contrast.
What I love most is how versatile this dish is, it works as an elegant side for dinner parties, but I’ve also been known to eat it as my whole meal when I’m feeling indulgent (no judgment!). The best part? While it tastes like something you’d order at a fancy restaurant, it only takes about 10 minutes of active prep time. My husband calls it “onion candy,” and trust me, once you try it, you’ll understand why!

Notes
Ingredients for Lemon Cream Onion Boil
One of the best things about this recipe is how few ingredients you need to make something so spectacular! Here’s what I always keep on hand:
- 4 large sweet onions, Look for ones that feel heavy for their size with tight, shiny skins (Vidalias are my favorite!)
- 2 tablespoons unsalted butter, That’s ½ tablespoon per onion, but who’s counting? I sometimes sneak in an extra dab!
- 1 tablespoon olive oil, The good stuff, it makes all the difference in those caramelized edges
- ½ teaspoon salt, I use kosher salt for better flavor distribution
- 1 tablespoon seasoning or sauce, This is where you can get creative (more on that below!)
Ingredient Substitutions & Notes
Need to tweak things? No problem! Here are my favorite swaps:
- Keto friends: Use sugar-free cream sauce instead of regular and swap in ghee if you prefer
- Lighter option: Cut butter to 1 teaspoon per onion and use cooking spray instead of olive oil
- Allium alternatives: Red onions work in a pinch but will be sharper, boil them 5 minutes longer
- Dairy-free: Coconut oil works beautifully in place of butter
The key is using what you love, this recipe is very forgiving!
Equipment Needed for Lemon Cream Onion Boil
You won’t need any fancy gadgets for this recipe, just a few basic kitchen tools that you probably already have:
- Melon baller or small spoon, My grandma’s old grapefruit spoon works perfectly for scooping out those onion centers
- Large pot, Big enough to comfortably fit all four onions with room to bob around
- Aluminum foil, For wrapping if you’re doing the roasted version (trust me, it’s worth it!)
- Baking dish, Just a simple one for roasting, I use my trusty 9×13 pan
That’s it! No special equipment needed to make this restaurant-worthy dish at home.
How to Make Lemon Cream Onion Boil
Okay, let’s get cooking! This recipe comes together in simple stages, but I’ll walk you through each one so you get perfect results every time. Don’t let the fancy name fool you, it’s really just boiling onions and adding deliciousness!
Boiling the Onions
First things first, fill your large pot with enough water to completely cover the onions (about 2 quarts for me). Bring it to a rolling boil while you prep the onions. Here’s my trick: after scooping out the centers, I make a few shallow slits in the onion layers with a paring knife, this helps them cook evenly. Gently lower them into the boiling water, reduce heat to a lively simmer, and set your timer for 20 minutes. Test tenderness by poking with a fork, you want resistance but no crunch!
Preparing the Filling
While those onions bob away, let’s make magic happen! Melt your butter (I sometimes add a garlic clove to infuse flavor) and mix it with the olive oil and salt. The key is getting this mixture between the onion layers, I use a small spoon to gently separate them and drizzle it in. For the filling, I alternate between spooning in the mixture or adding grated cheese, both are heavenly! Pro tip: let the onions drain upside down for a minute so excess water doesn’t dilute your flavors.
Roasting for Extra Flavor (Optional)
If you want next-level flavor (and trust me, you do), wrap each stuffed onion tightly in foil, shiny side in! Roast at 375°F for 15-20 minutes until gloriously tender. For golden perfection, unwrap and broil for 2-3 minutes at the end. That caramelized top? Absolute heaven!
Tips for the Perfect Lemon Cream Onion Boil
After making this dish dozens of times, I’ve learned a few tricks that make all the difference:
- Watch the clock! Overboiling turns onions mushy, pull them when they’re just fork-tender (think al dente pasta).
- Season in layers: I add a pinch of salt to the boiling water AND the filling for balanced flavor.
- Size matters: Pick onions roughly the same size so they cook evenly, no tiny ones getting lost!
- Broil carefully: That golden top can burn fast, I never step away during those last 3 minutes!
My secret? Letting them rest 5 minutes before serving, the flavors meld beautifully!
Serving Suggestions for Lemon Cream Onion Boil
Oh, the possibilities! These tender, buttery onions shine as a side but honestly, I’ve served them every which way. My favorite pairing? Juicy grilled chicken, the lemony onions cut through the richness perfectly. For summer nights, I’ll slice them over crisp greens with a tangy vinaigrette. Last Thanksgiving, I even served them alongside roast turkey, and let me tell you, they stole the show!
Storage & Reheating Instructions
Here’s my foolproof method for keeping these onions tasting fresh! Let them cool completely, then store in an airtight container, they’ll keep beautifully in the fridge for 3-4 days. When reheating, I skip the microwave (which makes them soggy) and pop them back in a 350°F oven for 10-15 minutes wrapped in foil. The butter melts back into perfection, and they taste just like fresh! For single servings, I’ll sometimes slice and sauté them quickly in a pan, makes the edges delightfully crispy.
Lemon Cream Onion Boil Nutritional Information
Now, let’s talk numbers! A basic Lemon Cream Onion Boil (without extra fillings) comes in at about 120 calories per onion, mostly from that glorious butter. Of course, this varies based on your ingredients, adding cheese or cream sauce will bump it up. The onions themselves pack vitamin C and fiber, making this side dish surprisingly nutritious. Just remember, my nutritionist friend always reminds me, these estimates change based on exact portion sizes and ingredient brands!
Lemon Cream Onion Boil FAQs
I get asked about this recipe all the time, here are answers to the most common questions:
Can I use red onions instead of sweet onions?
You can, but expect a sharper flavor! Red onions need about 5 extra minutes of boiling to mellow out. I sometimes add a pinch of sugar to balance their bite.
How do I know when the onions are done boiling?
They’re ready when a paring knife slides in with slight resistance, think “potato tender.” Overcooked onions lose their shape, so err on the firmer side.
Can I make these ahead of time?
Absolutely! Boil and stuff them up to 2 days ahead, then roast just before serving. The flavors actually improve as they sit!
What’s your favorite filling variation?
Hands down, lemon zest mixed into the butter with a sprinkle of thyme. But my husband swears by blue cheese crumbles, try both!
