I've gotta share my top way to cook onions and potatoes with herbs that'll fill your home with mouthwatering smells. After tweaking this at countless family meals, it's become my foolproof side dish that gets everyone excited. There's something about those golden edges with soft centers that nobody can turn down.
What Makes These Special
This dish has become my standby for everything from quick dinners to big holiday gatherings. The magic happens when basic ingredients turn into something wow-worthy. The potatoes get that perfect crunch while the onions turn sweet and jammy - it's seriously addictive.
Picking The Right Spuds
After trying tons of varieties, Yukon Golds work best for me. They get this buttery inside while still getting nice and crisp outside. For extra crunchiness, try Russets instead. Just cut everything the same size so it all cooks evenly.
Why Onions Matter
The onions aren't just a backup player here. I cut them into big chunks because they get incredibly sweet when roasted. That deep flavor they develop really takes everything up a notch.
What Gives The Taste
The extras and spices really transform everything. Fresh garlic is a must in my book, and rosemary brings amazing woodsy notes. My hidden trick? A pack of onion soup mix that brings so much extra flavor depth.

Smart Oil Choices
Here's something I figured out after many tries - mixing canola and olive oil works wonders. The canola helps everything get that amazing crispiness while the olive oil adds that wonderful rich taste.
Proper Pepper Touch
Go heavy with the black pepper. I always crack it fresh and use more than most recipes call for. It works so well with all the savory stuff going on and adds just enough warmth.
Prep Work
Your oven temp matters big time. I turn mine up to 450°F because that super hot oven gives you those crispy bits everyone loves. Always wait until it's completely hot before putting anything in.
Toss Everything
I actually enjoy this messy part. Throwing it all in a big pan and making sure every single piece gets coated. Getting that even layer of oil and spices means everything will brown beautifully.
Cooking Method
Starting with the pan covered helps soften everything, then taking the lid off browns it all up. Don't skip stirring halfway - it helps everything cook evenly. I usually sneak a taste right then to check if they're on track.

Why Two Oils Work
Combining oils isn't just fancy - it's practical. The olive oil brings great flavor but canola won't burn at high temps. Together they work wonders for the perfect finish.
Don't Crowd The Pan
My number one rule: give everything plenty of room. Those potatoes and onions need space to get properly crispy. Pack them too tight and they'll just steam each other instead of roasting.
Try Different Herbs
Rosemary's my go-to but playing with other herbs is fun too. Fresh thyme works beautifully, and oregano gives everything a Mediterranean feel. Sometimes I'll mix whatever's growing in my garden that day.
Mix It Up
For fun variety, I sometimes toss in sweet potato chunks for color contrast. When I'm feeling fancy, I'll sprinkle a tiny bit of brown sugar over everything during the last few minutes of cooking.
Turn Into Dinner
On busy nights, I throw in chunks of sausage or chicken pieces right with everything else. It all cooks together, and the meat juices make the potatoes taste even better.

Last-Minute Additions
Just before bringing it to the table, I add some bright touches. A handful of chopped parsley, some freshly grated Parmesan, or my personal fave - a little drizzle of thick balsamic. These small touches really make it pop.
Speedy Air Fryer Method
When I'm in a rush, I use my air fryer instead. You'll get the same crispiness in about half the time. Just remember to shake everything around midway through cooking.
Serve With Sauce
My kids love having something to dip into. I usually mix up a quick garlic mayo or put out some ranch. Those creamy sauces go great with the crunchy potatoes.
Add Some Kick
When we want something with a bit of zing, I toss in some red pepper flakes or a dash of smoked paprika. Start small - you can always add more, but that gentle heat really works with the herbs.
Cook Once, Eat Twice
These are great for making ahead. I cook a huge batch on weekends and warm up portions through the week. A few minutes in a hot oven or air fryer brings back that amazing crunch perfectly.

Common Questions
- → What's the reason for mixing canola and olive oil?
- Canola oil handles high heat better during baking, while olive oil brings nice flavor. Using both gives you the advantages of each type.
- → What's the point of covering potatoes at first?
- Starting with a cover lets the potatoes soften up inside before they get crunchy. This way you'll get that perfect contrast between the crispy exterior and soft center.
- → Is it okay to make this in advance?
- You can chop the veggies ahead, but for that amazing crunch, it's best to bake them right before you plan to eat.
- → Will dried rosemary work in place of fresh?
- Sure, just use about a teaspoon since dried herbs pack more punch than fresh ones. Fresh rosemary tastes better if you can get it, though.
- → Why cut the potatoes into 1/2-inch chunks?
- This size cooks through just right and gives you that nice crunch outside while staying soft inside. Bigger chunks would need more time in the oven.
