Caramelized Onion, (Sometimes Bacon), and Pecan Brussels Sprouts

The aroma still takes me back to Thanksgiving dinners at my Aunt Carol’s. While the turkey and mashed potatoes were always expected, it was her Brussels sprouts that were the real star. Sometimes they boasted the salty, smoky goodness of bacon; other times, the nutty crunch of pecans reigned supreme. But the constant? Those deeply caramelized onions, providing a sweet counterpoint to the slightly bitter sprouts, transforming them from a dreaded vegetable into a dish everyone fought over.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 8
• Dietary Type: Adaptable (Vegetarian, Gluten-Free, easily made Vegan)

Ingredients

• 1 large onion
• 1 lb Brussels sprouts
• ¼ cup butter (or olive oil for a vegan option)
• 1 cup pecan pieces (or crisp cooked bacon, crumbled)
• 1 teaspoon salt
• ½ teaspoon pepper

Equipment Needed

• Large skillet

Instructions

1. Begin by preparing the onion. Cut it in half, from root to tip, then thinly slice each half.
2. Next, prepare the Brussels sprouts. Trim the ends and remove any yellowed outer leaves. Cut each sprout in half, then thinly slice each half into shreds, similar to a chiffonade cut. This creates thin, easy-to-cook pieces.
3. Optional Step for Enhanced Flavor: For best results, place the sliced onion and shredded Brussels sprouts in separate bags and chill them in the refrigerator for at least 30 minutes, or up to 8 hours. Chilling helps to mellow the onion’s sharpness and allows the Brussels sprouts to crisp up better when cooked.
4. In a large skillet, melt the butter over medium heat. (For a vegan version, substitute with olive oil.)
5. If using pecans, add them to the melted butter and sauté for about 5 minutes, or until they are lightly toasted and fragrant. Keep a close watch to prevent burning. Remove the pecans from the skillet and set them aside. If using bacon, cook the bacon until crispy, remove from pan and set aside to cool, reserving 1 tbsp of bacon fat in the pan.
6. Add the sliced onion to the skillet (with the remaining melted butter or reserved bacon fat). Cook, stirring frequently, for approximately 15 minutes, or until the onion is deeply caramelized and golden brown. Don’t be afraid to let some edges get a little dark and crispy – this adds depth of flavor. The goal is a sweet, almost jam-like consistency.
7. Add the shredded Brussels sprouts to the skillet with the caramelized onions. Cook, stirring occasionally, for about 3-5 minutes, or until the Brussels sprouts are heated through and slightly tender-crisp. Avoid overcooking, as they can become mushy.
8. Return the toasted pecans (or crumbled bacon) to the skillet. Stir to combine all ingredients.
9. Season with salt and pepper to taste. Adjust seasoning as needed.
10. Serve immediately.

Expert Tips & Tricks

• Achieving Perfect Caramelization: The key to deeply caramelized onions is low and slow cooking. Don’t rush the process. Stir frequently, but allow the onions to develop color in between stirs. If the onions start to burn, lower the heat slightly and add a tablespoon of water to deglaze the pan.
• Brussels Sprouts Texture: Shredding the Brussels sprouts ensures even cooking and prevents them from being undercooked or overcooked. If you prefer a more roasted flavor, you can roast the shredded Brussels sprouts in a preheated oven at 400°F (200°C) for 10-12 minutes before adding them to the skillet.
• Flavor Boosters: For an extra layer of flavor, consider adding a splash of balsamic vinegar or a squeeze of lemon juice towards the end of cooking. A pinch of red pepper flakes can also add a subtle kick.
• Make-Ahead Option: The caramelized onions can be made ahead of time and stored in the refrigerator for up to 3 days. Simply reheat them in the skillet before adding the Brussels sprouts.
• Bacon Fat is Your Friend: If using bacon, cooking the onions in the rendered bacon fat adds an incredible smoky flavor that complements the Brussels sprouts perfectly.

Serving & Storage Suggestions

Serve these Caramelized Onion and Pecan Brussels Sprouts immediately as a side dish alongside roasted meats, poultry, or fish. They are also a great addition to vegetarian main courses like grain bowls or pasta dishes.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply sauté in a skillet over medium heat until warmed through. You can also reheat them in the microwave, but they may lose some of their crispness. Reheating in the oven is also an option, just spread them on a sheet pan and bake at 350F for 5-10 minutes. While freezing is not recommended due to texture changes, they are best enjoyed fresh.

Q: Can I make this recipe ahead of time?
A: The caramelized onions can be made ahead of time and stored in the refrigerator for up to 3 days. Simply reheat them in the skillet before adding the Brussels sprouts. For best results, add the pecans or bacon just before serving to maintain their crispness.
