Slow-Cooked Pork Rillettes with Tangy Pickled Red Onions

There’s something deeply satisfying about watching your dinner guests slather rich, savory pork rillettes onto a crisp keto cracker, top it with a vibrant pickled red onion, and experience that moment of pure culinary bliss. This traditional French preparation gets a low-carb makeover without sacrificing an ounce of its decadent character.

When I first discovered rillettes in a tiny bistro tucked away in Paris’s 6th arrondissement, I was forever changed. The owner—a boisterous man with hands the size of dinner plates—insisted I try his family’s century-old recipe. One bite in, and I understood why this rustic dish has survived the test of time. Years later, perfecting my keto version became something of an obsession, and darlings, the effort was entirely worth it.

A Brief History With a Keto Twist

Rillettes originated in Tours, France, where preserving meat in its own fat wasn’t just delicious—it was necessary before refrigeration existed. Traditionally served as a humble farmer’s meal, it has since found its way onto the most sophisticated charcuterie boards. The beauty of this dish? It’s naturally low-carb when you skip the baguette. The French peasants who invented it would be absolutely gobsmacked to learn their preservation technique would one day be the darling of dieters worldwide.

Why This Recipe Works

This keto adaptation of pork rillettes is a triumph for several compelling reasons:

  • The slow-cooking process breaks down tough collagen into gelatin, creating that signature melt-in-your-mouth texture without any carb-heavy additives.
  • By using belly and shoulder cuts, you’re maximizing fat content—perfect for hitting those keto macros while delivering incredible flavor.
  • The tangy pickled red onions cut through the richness beautifully without adding significant carbs.
  • It can be prepared days in advance, actually improving in flavor as it rests.
  • The recipe makes enough to entertain with style or enjoy throughout the week as a protein-packed snack.

Ingredients

Keto Slow-Cooked Pork Rillettes with Tangy Pickled Red Onions

For the Rillettes:

  • 1.5 pounds (680g) pork belly, skin removed, cut into 2-inch chunks
  • 1.5 pounds (680g) pork shoulder, cut into 2-inch chunks
  • 3 tablespoons duck fat (or lard)
  • 6 cloves garlic, lightly crushed
  • 2 bay leaves
  • 4 sprigs fresh thyme
  • 2 teaspoons sea salt
  • 1 teaspoon white pepper
  • 1/2 teaspoon ground nutmeg
  • 1/4 cup (60ml) dry white wine (optional, adds ~2g carbs to entire recipe)
  • 1/4 cup (60ml) water

For the Pickled Red Onions:

  • 1 medium red onion, thinly sliced
  • 1/2 cup (120ml) apple cider vinegar
  • 1/4 cup (60ml) water
  • 1 tablespoon erythritol or preferred keto sweetener
  • 1 teaspoon sea salt
  • 1/2 teaspoon black peppercorns
  • 1 garlic clove, sliced
  • 1 small bay leaf

Instructions

For the Rillettes:

  1. Preheat your oven to 275°F (135°C).

  2. Season the pork chunks generously with salt, white pepper, and nutmeg, rubbing the spices into the meat.

  3. In a large Dutch oven or heavy-bottomed ovenproof pot, melt the duck fat over medium heat. Add the pork pieces (working in batches if necessary) and brown on all sides, about 2-3 minutes per side.

  4. Return all meat to the pot, add the crushed garlic, bay leaves, and thyme sprigs. Pour in the white wine (if using) and water.

  5. Cover the pot tightly with a lid and transfer to the preheated oven. Cook slowly for 3-4 hours, until the meat is incredibly tender and falls apart when pressed with a fork.

  6. Remove from the oven and let cool slightly. Fish out and discard the bay leaves and thyme sprigs.

  7. Using two forks or clean hands, shred the meat finely while it’s still warm, mixing it with the rendered fat in the pot. The texture should be somewhat coarse but cohesive.

  8. Taste and adjust seasoning if needed, then pack the mixture firmly into ceramic ramekins or glass jars, pressing down to remove any air pockets.

  9. Pour any remaining fat from the pot over the top of each container to create a protective seal. This will help preserve the rillettes.

  10. Refrigerate for at least 24 hours before serving to allow flavors to develop and meld.

For the Pickled Red Onions:

  1. Place sliced red onions in a clean glass jar.

  2. In a small saucepan, combine vinegar, water, erythritol, salt, peppercorns, garlic, and bay leaf. Bring to a simmer over medium heat, stirring until salt and sweetener dissolve completely.

  3. Pour the hot liquid over the onions, ensuring they’re completely submerged. Let cool to room temperature.

  4. Seal the jar and refrigerate for at least 2 hours before serving, though overnight is preferable for best flavor.

Tips and Variations

  • Perfect Pairings: Serve your rillettes with keto seed crackers, cucumber rounds, or butter lettuce cups for a truly low-carb experience.

  • Fat Adjustments: If your rillettes seem dry after cooling, warm some additional duck fat and mix it in until you reach your desired consistency.

  • Herb Variations: Try adding 1/2 teaspoon of ground cloves or a tablespoon of chopped fresh rosemary for different flavor profiles.

  • Storage Savvy: Properly sealed with a fat cap, these rillettes will keep in the refrigerator for up to two weeks—if they last that long!

  • Duck Alternative: For a truly luxurious version, substitute half the pork with duck legs for duck and pork rillettes.

  • Spice it Up: Add 1/4 teaspoon of cayenne pepper to the meat before cooking for a subtle heat that complements the richness.
