How to Make Roasted Brussels Sprouts & Garlic Mashed Potatoes
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup later.
Prepare Your Brussels Sprouts: Rinse and trim the Brussels sprouts by cutting off the stem ends. Slice them in half for even roasting and better caramelization.
Toss with Olive Oil: In a bowl, combine halved Brussels sprouts with olive oil, salt, and pepper. Ensure each sprout is coated evenly to achieve that perfect roast.
Roast Until Golden: Spread the coated Brussels sprouts in a single layer on your baking sheet. Roast in the preheated oven for 20-25 minutes until they are golden brown and crispy on the edges.
Boil Your Potatoes: While your sprouts roast away, peel and chop russet potatoes into equal pieces. Boil them in salted water until fork-tender—about 15-20 minutes should do it!
Mash with Garlic Bliss: Drain your potatoes and return them to the pot over low heat. Add roasted garlic cloves (smash them first), butter, salt, and pepper. Mash until creamy and dreamy!
Add Final Touches: If you’re feeling fancy, mix in some grated Parmesan cheese into your mashed potatoes or sprinkle it over those fabulous roasted Brussels sprouts before serving.
And there you have it! You’ve turned simple veggies into an unforgettable side that will leave everyone asking for your secret recipe. Enjoy every bite while relishing in your newly earned culinary prowess!

Perfecting the Cooking Process
Timing is everything in this recipe. Start by preheating your oven to 400°F (200°C) while you prepare the Brussels sprouts.

This method keeps everything warm and ready to serve simultaneously.
Add Your Touch
Feel free to get creative! Swap out Brussels sprouts for broccoli or cauliflower if you prefer something different. Experiment with spices like paprika or add grated cheese to the mashed potatoes for a creamy twist. Fresh herbs like thyme or rosemary can elevate the flavor profile beautifully, making your dish truly unique.
Storing & Reheating
Store any leftovers in an airtight container in the fridge for up to three days. To reheat, place the garlic mashed potatoes in a saucepan over low heat, stirring occasionally until warmed through. For the Brussels sprouts, pop them back into a hot oven for about 10 minutes to regain that crispy texture.

FAQ
What are some common mistakes when roasting Brussels sprouts?
A common mistake is overcrowding the baking sheet, which causes steaming rather than roasting. Make sure there’s enough space between each sprout so they can crisp up nicely! Another pitfall is not preheating your oven properly; if it’s not hot enough, you won’t get that desired golden-brown exterior.
Can I make garlic mashed potatoes ahead of time?
Absolutely! You can prepare garlic mashed potatoes a day in advance. Just store them in an airtight container in the fridge after mashing and reheat them gently before serving. Add a splash of milk or cream during reheating to restore creaminess if needed.
How do I ensure my roasted Brussels sprouts are crispy?
To achieve those perfectly crispy sprouts, make sure they are completely dry before tossing them in oil and seasoning. Additionally, roasting at a high temperature helps develop that crunchy exterior everyone loves!
Can I use frozen Brussels sprouts instead?
While fresh Brussels sprouts yield the best results, you can use frozen ones in a pinch! Just be sure to thaw them completely and pat them dry before roasting to avoid excess moisture.
