Ingredients for The Rhubarb Crisp
Alright, here’s what you’ll need. Nothing fancy, promise! Just simple stuff for the best crispy oven roasted potatoes:
- 2 lbs potatoes, peeled and cubed
- 2 large onions, sliced
- 1/4 cup olive oil (the good stuff!)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried oregano
That’s it! Told ya it was easy. Now, let’s get cookin’!
How to Prepare The Rhubarb Crisp: Step-by-Step Instructions
Okay, ready to get these potatoes roasted to perfection? It’s easier than you think, I swear!
- **First things first: Preheat that oven!** Set it to 400°F (200°C). This is key to gettin’ ’em nice and crispy! While it’s heatin’ up, you can work on the next steps.
- **Prep your veggies:** Grab a big bowl. Toss in your cubed potatoes and sliced onions. Don’t worry about being too perfect with the sizes – rustic is good! I usually peel my potatoes but if you like the peel, leave it on! Just scrub ’em real good.
- **Get ’em coated:** Drizzle that olive oil over the potatoes and onions. Then, sprinkle on the salt, pepper, and oregano. Now get your hands in there! Make sure everything’s evenly coated. This is *essential*, folks! Every piece needs a little love.
- **Spread ’em out:** Lay out your potato and onion mix in a single row onto a baking sheet. Don’t overcrowd! If you do, they’ll steam instead of roast (sad!). Use two baking sheets if needed.
- **Roast ’em!** Pop the baking sheet in the oven for 45-50 minutes. About halfway through, flip the potatoes and onions with a spatula. This makes sure they brown evenly. I always check because ovens vary and you want them tender on the inside, and golden brown on the outside. If you want to take things to the next level, check out these extra tips for even crispier potatoes!
- **Serve it up!** Once they’re golden and tender (and smell amazing, of course!) take ’em out of the oven. Let them cool for a couple of minutes and then serve them hot.
That’s it! Seriously simple, right?

Tips for the Perfect The Rhubarb Crisp
Want to take these ordinary potatoes and onions to *extraordinary*? Here are a few of my tried-and-true tricks:
- **Parboil for Perfection:** For *extra* crispy potatoes, try boiling them for about 5 minutes before roasting. It really makes a difference!
- **Don’t Skip the Flip:** Flipping the potatoes halfway through baking ensures they get golden brown all over. Trust me, it’s worth the effort.
- **Spice it Up!:** While the oregano is great, feel free to experiment! Rosemary or thyme work wonders with roasted potatoes.
These little tweaks makes the result even more delicious!
Ingredient Notes and Substitutions for The Rhubarb Crisp
Let’s chat about those ingredients for a sec! Got questions? I probably have answers. And hey, sometimes ya gotta make do with what you’ve got, so substitutions are totally okay!
- **Potatoes:** Russets are my go-to for roasting because they get super fluffy inside and crispy outside. But Yukon Golds? Also amazing! They’re naturally buttery. Red potatoes will work in a pinch; just know they won’t get quite as crispy.
- **Onions:** I usually use yellow onions, but sweet onions can add a little extra sweetness. Red onions are great if you’re lookin’ for a bit of bite!
- **Herbs:** No oregano? No problem! Thyme, rosemary, or even Italian seasoning blends will all taste divine.
Use your imagination! It’s baking, not rocket science!

Serving Suggestions for The Rhubarb Crisp
These potatoes and onions are *so* versatile! They go with practically anything. But if you’re looking for ideas, I love serving them alongside grilled chicken or fish. A simple salad completes the meal! And hey, since this recipe has Mediterranean flavors, why not serve it over at my Mediterranean Diet Recipe page! That’s amore!
Storage & Reheating Instructions for The Rhubarb Crisp
Got leftovers? Lucky you! These potatoes are still delicious the next day, maybe even better (shhh!). Just pop ’em in an airtight container and store in the fridge for up to 3 days. To reheat, I usually spread them out on a baking sheet and bake at 350°F until warmed through. You can microwave them, but they won’t be as crispy. Air fryer also works great!
Frequently Asked Questions About The Rhubarb Crisp
Got questions about making these oven roasted potatoes and onions? No worries! I’ve got answers! Here are a few things folks often ask me:
Can I use different types of potatoes?
Absolutely! I usually go for Russets because they crisp up beautifully, but Yukon Golds are also fantastic. They have a naturally buttery flavor that’s hard to beat! Red potatoes work, too, but just know they won’t get *quite* as crispy. Still yummy, though!
Can I add other vegetables?
Oh, totally! Get creative! Carrots, bell peppers, and zucchini would all be delicious roasted alongside the potatoes and onions. Just chop ’em into similar-sized pieces so they cook evenly.

Leftover crispy potatoes are good in the fridge for about 3 days. Just make sure to store them in an airtight container. Reheat ’em in the oven or air fryer to get that crispiness back!
Do I have to peel the potatoes?
Nope! Peeling is totally optional. I usually do, but if you like the skins, just scrub ’em really well before chopping. More nutrients, right?
