Ingredients for Baked Tennessee Onions
Here’s everything you’ll need to make this delectable side:
- 4 large sweet onions (Vidalia or Texas Sweet preferred)
- 1/2 cup shredded cheddar cheese
- 1/4 cup grated Parmesan cheese
- 4 tablespoons unsalted butter, melted
- 1 teaspoon garlic powder
- 1 teaspoon smoked paprika 🌶️
- 1/2 teaspoon dried thyme
- Salt and pepper to taste 🧂
- Fresh parsley, for garnish
Pro Tip: Choosing the right onions is key. Vidalia or Texas Sweet onions offer just the right amount of natural sweetness and tenderness once baked.
Kitchen Equipment You’ll Need
- Sharp knife
- Cutting board
- Baking dish (9×13 works well)
- Aluminum foil
- Small mixing bowl (for the melted butter and spices)
- Measuring spoons
- Cheese grater (if grating your own cheese — highly recommended!)
How to Make Baked Tennessee Onions
Step 1: Prep the Oven and Onions
Preheat your oven to 375°F (190°C). Peel the onions, slice off their tops, and cut each onion into quarters — but keep the root intact so they hold together during baking.
Step 2: Season and Butter the Onions
Place the prepped onions into your baking dish. Drizzle them generously with the melted butter. In a small bowl, mix the garlic powder, smoked paprika, dried thyme, salt, and pepper, then sprinkle this aromatic blend all over the onions.
Step 3: Bake Covered
Cover the dish tightly with aluminum foil and bake for 30 minutes. This step ensures the onions become fork-tender and absorb all the buttery, seasoned goodness.
Step 4: Add the Cheesy Goodness
Uncover the onions, sprinkle them with the shredded cheddar and grated Parmesan cheeses, and return the dish to the oven for another 15 minutes, or until the cheese is bubbling, golden, and slightly crispy around the edges.
Step 5: Garnish and Serve
Remove from the oven, sprinkle fresh parsley on top for a pop of color and freshness, and serve hot!
Serving Suggestions
Baked Tennessee Onions are incredibly versatile. Here are some ways to enjoy them:
- As a side to grilled steaks, barbecue ribs, roasted chicken, or pork chops.
- Alongside mashed potatoes for a double hit of comfort food.
- Tucked into burgers for an extra punch of sweet, cheesy goodness.
- With a green salad and crusty bread for a lighter meal.
Drink Pairing: A glass of crisp Sauvignon Blanc or a smoky bourbon cocktail complements the richness of this dish beautifully.
Recipe Variations and Shortcuts
Switch up the cheese: Swap cheddar for pepper jack, Gruyère, or mozzarella for a different flavor profile.
Add bacon: Crumble cooked bacon over the onions before adding the cheese for an even more decadent dish.
Make it spicy: Add a pinch of cayenne pepper to the butter and seasoning mix for extra heat.
Use red onions: For a slightly sharper flavor, red onions can be substituted, although the final taste will be less sweet.
Shortcut tip: If you’re short on time, microwave the onions for 5 minutes before baking to cut down on oven time.
How to Store Leftovers
If you somehow manage to have leftovers, here’s how to keep them fresh:
- Refrigerator: Store in an airtight container for up to 4 days.
- Reheating: Warm them gently in the oven at 350°F, covered, until heated through. You can also microwave them, but the oven helps keep the cheese melty and the texture intact.
Freezing tip: It’s not recommended to freeze Baked Tennessee Onions as the texture of the onions can become mushy upon thawing.
Frequently Asked Questions (FAQ)
Can I make Baked Tennessee Onions ahead of time?
Yes! You can assemble the dish up to the first bake (before adding the cheese) and refrigerate it. When ready to serve, simply bake covered, then add cheese and finish baking uncovered.
What’s the best way to cut the onions?
Cutting the onions into quarters but keeping the root intact helps them stay together during baking and makes for a beautiful presentation.
What type of cheese melts best for this recipe?
Sharp cheddar and Parmesan are a perfect combo because they melt beautifully while adding distinct layers of flavor. For a gooier texture, add a little mozzarella to the mix.
Can I use pre-shredded cheese?
While convenient, pre-shredded cheese often contains anti-caking agents that prevent it from melting smoothly. Freshly shredding your own cheese is best for optimal gooeyness and flavor.
Are these onions spicy?
The smoked paprika gives a subtle smoky warmth but not much heat. If you prefer more spice, feel free to add a pinch of cayenne pepper.
