1. Classic Cheesy Garlic Stuffed Onions

Sometimes, you don’t need fancy. Sometimes, you just want cheese + garlic + onion = happiness.

• Salt & pepper to taste
• Fresh parsley for garnish

Instructions

1. Preheat your oven to 375°F (190°C).

Ingredients

Tips to Nail Any Stuffed Onion Recipe

• Choose the right onion. Sweet or yellow onions soften beautifully, while red onions add a sharper kick.
• Don’t skip parboiling or roasting. Raw onions stuffed and baked can stay tough. Give them a head start.
• Hollow smartly. Leave at least 2 onion layers so the filling doesn’t collapse.
• Think balance. Pair sweet onions with salty fillings (like feta or beef) and mild onions with bold flavors (like lentils + smoked paprika).

Why You’ll Love Cooking Stuffed Onions

Cooking stuffed onions feels like a magic trick. You take something ordinary, scoop it out, fill it with love (okay, and cheese), then bake it into something that makes people go “whoa.”

They’re versatile enough to be a side dish or a full-on main. They also look way fancier than the effort you actually put in. Ever had a dinner guest ask, “Wow, how long did that take you?” while you secretly know it was 30 minutes tops? Yeah, it’s that kind of dish. 🙂
