What to Serve with Onion Tart? 15 Best Side Dishes

Onion Tart

Onion tart is the perfect dish for a summer BBQ or picnic.

It’s light, fluffy, and full of flavor.

And it pairs well with just about anything!

Here are 15 side dishes to serve with onion tart:

1. Arugula Salad

Arugula is kind of like the salad version of onion.

I like to add a bit of acidity to balance out the sweetness of the onion, so I’ll add a squeeze of lemon juice and a sprinkle of vinegar.

I’ll also add some shaved Parmesan cheese and a few croutons for extra flavor and texture.

2. Grilled Corn on The Cob

On a warm summer day, there’s nothing better than grilled corn on the cob.

This side dish is the perfect accompaniment to a delicious onion tart.

  1. To make it, simply grill the corn on a preheated grill, turning occasionally, until it’s evenly charred.
  2. Then, brush it with a little bit of butter or olive oil and season it with salt and pepper to taste.
  3. Serve immediately.

3. Roasted Brussels Sprouts

Crunchy, small, and intensely flavorful, Brussels sprouts are a great side dish to any meal.

When roasted, they become slightly sweet and very tender.

  1. To roast Brussels sprouts, simply trim them and toss with olive oil and salt.
  2. Then roast in a preheated oven at 400 degrees Fahrenheit for about 20-25 minutes.

When serving Brussels sprouts with onion tart, be sure to top the tart with some roasted Brussels sprouts.

The combination of the two dishes is simply heavenly!

4. Baked Potato

It’s time to turn on the oven and bake a potato!

The perfect side dish to accompany your savory tart, a baked potato is simple and delicious.

  1. Just scrub your potato clean, then poke a few holes in it with a fork.
  2. Rub a little bit of olive oil on the skin, then sprinkle with salt.
  3. Bake in a preheated oven for about an hour, or until the potato is nice and soft.

5. Roasted Sweet Potatoes

If you like some crunch with your creamy onion tart, roasted sweet potatoes are the perfect side dish.

  1. Just slice them up into thin wedges and roast in a hot oven until crispy on the outside and fluffy on the inside.
  2. Serve with a dollop of onion tart on top and enjoy!

6. Honey Glazed Carrots

You can also add some beautiful color to your plate by serving honey glazed carrots with your tart.

  1. For this healthy and flavorful side dish, simply combine carrots with a bit of honey, some fresh thyme, and a touch of olive oil.
  2. Then roast in a hot oven until the carrots are tender and glazed.

This easy side dish is the perfect complement to any savory tart.

7. Sautéed Green Beans with Garlic

If you have a skillet large enough to fit the onion tart, you can cook the green beans (See Also: 42 canned green bean recipes) right in the same pan.

Otherwise, cook them in a separate pan.

  1. Start by trimming the ends off the green beans.
  2. Then, sauté them in a bit of olive oil over medium heat.
  3. Add some minced garlic and cook until the green beans are tender.
  4. Season the green beans with salt and pepper to taste.
  5. Serve them alongside the onion tart.

Here are some tips for making the perfect sautéed green beans:

  • Trim the ends off the green beans before cooking them. This will help them cook evenly.
  • Don’t overcook the green beans. They should be tender, but still have a bit of crunch.
  • Season the green beans with salt and pepper to taste. This will bring out their flavor.

8. Macaroni and Cheese

This family favorite side dish is the perfect pairing for a light and fluffy onion tart.

  1. To prepare, simply cook macaroni noodles according to package instructions.
  2. Once cooked, drain the noodles and mix in your favorite cheese sauce. For an extra creamy dish, stir in some milk or cream.
  3. Then, top with shredded cheese and bake in a preheated oven until cheese is melted and bubbly.

Here are a few tips for the perfect mac and cheese:

  • Use a good quality cheese for the sauce. This will make all the difference in flavor.
  • Don’t overcook the noodles. They should be tender, but not mushy.
  • Be sure to bake the dish long enough to melt the cheese and create a bubbly, golden brown top.

9. Mashed Potatoes

What can be easier than mashing some potatoes?

But there are a few things to keep in mind to make sure your mashed potatoes are perfect every time:

  • Start with starchy potatoes. Russet or Yukon Gold potatoes are ideal.
  • Boil the potatoes in salted water. This will add flavor and help to prevent them from overcooking.
  • Use a potato ricer or masher to get the perfect consistency.
  • You don’t want your potatoes to be too chunky or too smooth.
  • Add in some butter, milk, and salt to taste. For a healthier option, you can use olive oil instead of butter.

10. Creamed Spinach

Yeah, spinach doesn’t have to taste boring and bland.

This creamed spinach recipe is rich, creamy, and full of flavor.

Plus, it’s super easy to make.

And it pairs perfectly with an onion tart.

Here are three tips for making the best creamed spinach:

  1. Use fresh spinach. It tastes so much better than frozen.
  2. Use a good quality cream cheese. It makes a big difference in taste.
  3. Add a little bit of nutmeg. It really enhances the flavor.

11. Kale Salad

Whether you make your kale crunchy or soft, this salad is the perfect side to an onion tart.

The key to a good kale salad is in the dressing – make sure it is flavorful and coats the kale leaves evenly.

For an extra boost of flavor, add some chopped onions, garlic, or herbs to the dressing.

Here’s how I do it:

  1. Remove the tough stems from the kale leaves before chopping.
  2. Massage the dressing into the kale leaves for a minute or two to soften them up.
  3. Add some chopped nuts or seeds for a crunchy texture.

12. Roasted Asparagus

This long, green veggie is a great side to any meal, but goes especially well with a tart.

Here’s how to do it:

  1. Preheat your oven to 400 degrees Fahrenheit.
  2. Cut the asparagus into 1-inch pieces.
  3. Spread the asparagus on a baking sheet and roast for 10-12 minutes.

13. Quinoa Salad

Known for its healthy and nutty taste, quinoa is a great addition to any meal.

This quinoa salad is a simple and flavorful side dish that goes great with onion tart.

  1. To make the salad, simply cook the quinoa according to package instructions.
  2. Then, mix in your desired vegetables (I recommend red bell peppers, cucumbers, and tomatoes) and dressing (a vinaigrette or Italian dressing works well).
  3. For an extra boost of flavor, top the salad with crumbled feta cheese or chopped fresh herbs.

14. Farro Salad

Have you tried farro salad before?

I think it makes the perfect side dish for a summer BBQ or picnic.

Here are three tips for preparing it:

  • Cook the farro ahead of time so it has time to cool.
  • Add in some chopped fresh parsley or basil for extra flavor.
  • Use a vinaigrette dressing instead of a cream-based dressing to keep it light.

15. Wheat Berry Salad

Lastly, here’s an interesting one – wheat berry salad.

This is a great side dish to onion tart because it is light and fluffy, but also has a lot of flavor.

Plus, it pairs well with just about anything.

Here are three tips for preparing wheat berry salad:

  • Cook the wheat berries ahead of time so they are soft and fluffy.
