Equipment

  • 1 Large Baking Sheet
  • 1 Large Pot For cooking pasta
  • 1 Large Mixing Bowl
  • 1 Whisk For dressing
  • 1 Sharp Knife & Cutting Board For vegetable preparation

Ingredients
  

Main

  • 4 Tablespoons Thrive™ Algae Oil – divided
  • 1 Cup Cooked Pasta of Choice I used Acini di Pepe
  • 4 Cups Cubed Butternut Squash
  • 16 ounces Brussels Sprouts – halved then quartered
  • 1/2 Cup Raw Pecans – roughly chopped
  • 1 Cup Pomegranate Arils dried cranberries can be used instead
  • 1/4 Cup Thrive™ Algae Oil
  • 2 Tablespoons Apple Cider Vinegar
  • 1 teaspoon Stone Ground Mustard
  • 1 Tablespoon Pure Maple Syrup
  • Zest of 1 Orange
  • 1 Tablespoon Fresh Orange Juice
  • 1/4 teaspoon Sea Salt
  • 1/8 teaspoon Ground Pepper

Instructions
 

  • Preheat your oven to 400°F (200°C).
  • On a large baking sheet, toss the cubed butternut squash and quartered Brussels sprouts with 2 Tablespoons of algae oil, a pinch of sea salt, and ground pepper. Spread them in a single layer.
  • Roast the vegetables for 20-25 minutes, or until tender and caramelized, flipping halfway through to ensure even browning.
  • While the vegetables are roasting, cook your chosen pasta according to package directions until it is al dente. Drain well and set aside.
  • In a small bowl, whisk together the remaining 1/4 Cup algae oil, apple cider vinegar, stone ground mustard, pure maple syrup, orange zest, orange juice, the remaining sea salt, and ground pepper until the dressing is well emulsified.
  • Optional: Lightly toast the roughly chopped pecans in a dry skillet over medium heat for 3-5 minutes until fragrant, stirring occasionally to prevent burning.
  • In a large mixing bowl, combine the cooked pasta, roasted butternut squash, roasted Brussels sprouts, toasted pecans (if using), and pomegranate arils.
  • Pour the prepared dressing over the pasta and vegetable mixture.
  • Gently toss all ingredients to ensure they are evenly coated with the dressing.
  • Taste and adjust seasoning (salt and pepper) if necessary before serving warm or at room temperature.

Notes

For optimal roasting, ensure butternut squash and Brussels sprouts are cut into similar sizes for even cooking. Avoid overcrowding the baking sheet; use two if necessary to allow proper caramelization and prevent steaming. Cook pasta al dente, as it will absorb some of the dressing over time. Toasting the pecans beforehand will significantly enhance their nutty flavor and add a delightful crunch. The orange zest and juice in the dressing provide a crucial bright, acidic counterpoint to the richness of the roasted vegetables and sweetness of the maple syrup.

Equipment

  • 1 Cutting Board
  • 1 Sharp Knife
  • 1 Measuring Cups/Spoons
  • 1 Small Saucepan
  • 1 Heatproof Jar or Bowl

Ingredients
  

Main

  • 1/2 cup apple cider vinegar
  • 1 tablespoon sugar
  • 1 1/2 teaspoons kosher salt
  • 1 red onion thinly sliced

Instructions
 

  • Thinly slice the red onion using a sharp knife or mandoline.
  • In a small saucepan, combine the apple cider vinegar, sugar, and kosher salt.
  • Heat the mixture over medium heat, stirring occasionally, until the sugar and salt are completely dissolved and the liquid is simmering gently.
  • Place the thinly sliced red onion into a heatproof jar or bowl.
  • Pour the hot pickling liquid over the sliced onions, ensuring they are fully submerged.
  • Gently press the onions down with a spoon if necessary to keep them submerged in the brine.
  • Allow the onions to cool to room temperature on the counter.
  • Once cooled, cover the jar or bowl and refrigerate for at least 30 minutes before serving, or longer for more intense flavor.

Notes

For optimal results, ensure the red onion is sliced as thinly as possible; this allows for faster pickling and a more delicate texture. When heating the pickling liquid, aim for a gentle simmer, not a vigorous boil, to dissolve the sugar and salt without significantly reducing the vinegar. You can experiment with adding a few peppercorns, a bay leaf, or a sprig of fresh dill to the brine for added aromatic complexity. These pickled onions are incredibly versatile and elevate everything from tacos and sandwiches to salads and grilled meats.

The secret to quick pickled onions is cutting them thin 1/8 inch. Thinly cut onions will soften in a short time and absorb the brine in only 30 minutes. A sharp chef’s knife will do, but a mandoline makes it easy, producing even paper thin slices. Need more crunch? Cut thicker (1/4 inch), but realize they will take several hours or overnight to fully pickle. Choose according to your schedule and texture preference either way, the result is great.

Making the Ideal Brine

The brine is where this recipe shines. Mixing apple cider vinegar and distilled white vinegar provides a sweet, fruity depth I adore. Distilled white vinegar is okay if you’re out of apple cider vinegar, or try rice vinegar for a lighter flavor or red wine vinegar for depth. Every option brings a different personality to the table, so this recipe can be changed infinitely based on what you have in your pantry.

The Sweetness Factor

Sweetness is important for balance. Maple syrup or honey brings not only sweetness but a deep, earthy richness that sugar simply can’t provide. They mellow the vinegar tang and balance the onion bite, making it addictive. Omitting the sweetener makes the pickles too tart, so don’t do it! It’s a tiny addition that makes a great big difference.

Equipment

  • 1 Saucepan Medium-sized for heating pickling liquid
  • 1 Sharp Knife Or mandoline for thin, even onion slices
  • 1 Cutting Board
  • 1 Measuring Cups and Spoons
  • 1 Heatproof Jar with Lid For pickling and storage

Ingredients
  

Main

  • 3/4 cup white vinegar
  • 3 tablespoons sugar
  • 1/4 teaspoon salt
  • 1 bay leaf
  • 5 allspice berries
  • 5 whole cloves
  • 1/4 teaspoon fennel seeds
  • 1/4 teaspoon coriander
  • chile pepper
  • 1 large red onion peeled, and thinly sliced into rings

Instructions
 

  • Peel the red onion and thinly slice it into rings. Aim for uniform thickness for even pickling.
  • In a medium saucepan, combine the white vinegar, sugar, salt, bay leaf, allspice berries, whole cloves, fennel seeds, coriander, and chile pepper.
  • Bring the mixture to a simmer over medium heat, stirring occasionally until the sugar and salt are fully dissolved. Let it simmer gently for 2-3 minutes to allow the spices to infuse.
  • While the liquid is simmering, carefully pack the thinly sliced red onion rings into a clean, heatproof jar.
  • Once the pickling liquid has simmered, remove it from the heat.
  • Carefully pour the hot pickling liquid over the sliced onions in the jar, ensuring all onion slices are fully submerged.
  • Allow the jar to cool completely to room temperature on the counter.
  • Once cooled, secure the lid on the jar and transfer it to the refrigerator.
  • Allow the onions to pickle for at least 30 minutes, but ideally 2-4 hours or overnight, for best flavor development.
  • Serve the quick pickled red onions as a condiment or garnish, and store any leftovers in the refrigerator for up to 2-3 weeks.

Notes

Achieving uniformly thin red onion slices is paramount for even pickling and ideal texture; a mandoline is highly recommended for consistency. For a deeper flavor, lightly toast the whole spices (allspice, cloves, fennel, coriander) in a dry pan for 30-60 seconds before adding them to the vinegar solution. Ensure the pickling liquid comes to a full simmer to properly dissolve the sugar and salt and extract the spice essences. While you can use the onions after 30 minutes, allowing them to steep for at least 2-4 hours, or even overnight, significantly enhances their flavor and tenderness. Always ensure the onions are fully submerged in the liquid for proper pickling and longevity. Store refrigerated for optimal crispness and flavor for up to 2-3 weeks.

A Note on the Aroma

Pickling gives your kitchen a certain vinegar smell. It’s part of the deal, but a good vent or an open window gets the job done. The small hassle is worth it for the flavor these onions add to each and every dish. They’re a condiment superhero, adding a crunchy, spicy sweet finish to everything they come in contact with.

Customizing Your Brine

Now let’s get innovative. The brine is your palette, and you can make it your own. Use the apple cider and distilled vinegar combination for a sweet tangy foundation, or experiment with rice vinegar for a delicate hand or red wine vinegar for richness. For serious punch, use ¾ cup Seville orange juice (or ½ cup orange juice and ¼ cup lime juice) for citrusy, tropical flavor reminiscent of Yucatan cuisine.

Sweetener Options

Maple syrup or honey are my go to choices, but use granulated sugar if that’s all you have, particularly for a Mexican style pickle. Agave or brown sugar will lend a caramel like depth. Whatever you use, sweetness tempers the force of the vinegar so the flavor never feels too harsh.

Adding a Flavor Kick

Looking to heat things up? In addition to red pepper flakes, slice in some jalapeños for an intensified burn or habaneros for an explosive kick (use caution!). Thinly sliced garlic provides rich depth, ideal for Mediterranean or Latin cuisine. Whole peppercorns, mustard seeds, coriander, fennel, star anise, or cumin seeds add unusual warmth and texture. Fresh herbs such as thyme, rosemary, dill, or bay leaves provide aromatic notes, with citrus zest lemon, lime, or orange providing a bright lift.

Visual Appeal with Beets

For a beautiful twist, include a peeled, thinly sliced small beet in the brine. It colors the onions a dramatic beet red, ideal for salads or cheese plates. The beet provides a hint of earthy flavor without dominating the onion’s flavor, producing a gorgeous and rich layer.

Taming Onion Intensity

If uncooked onions are too pungent, par blanch them. Boil 2 cups of water, pour it over the chopped onions in a fine mesh strainer, and drain before adding to the brine. It mollifies their bite but retains them crisp, ideal for a milder pickle.
