Sarah Grueneberg grew up in Texas where she spent a lot of time on her grandparents’ cattle farm, eating food from scratch and building up an understanding of the sourcing of ingredients. Four years at legendary Chicago restaurant Spiaggia got her interested in Italian food and she made her first of many trips to Italy in 2009. At her own pasta-focused Italian restaurant, Monteverde, she is deeply inspired by regional Italian food rendered with signature Sarah Grueneberg creativity and flair.

I love anything on a stick and always have at least one skewer on the menu. The Italians are so creative when it comes to their spiedini and arrosticini - they’re a great way to show off the Wagyu coulotte steak too.   By thinly slicing the meat and threading it onto skewers, you are able to highlight the intense marbling of the meat while quickly cooking it, keeping it juicy and tender. You can pair the Wagyu with many different condiments. A few seasonal ones I keep in my back pocket are charred pepper peperonata, tonnato-style aioli and this radicchio orange mostarda. 

Recipe TC1 Right Story - Sarah Grueneberg's Spiedini Skewers


  • 1 Westholme coulotte  

  • 12 x 25-30cm (10-12 in) bamboo skewers, soaked in water for 1 hour 

  • coarse flaky sea salt, like Maldon 

  • black pepper, freshly cracked 

  • extra virgin olive oil 

  • dill sprigs, for garnish 

  • toasted pistachios, finely chopped, for garnish 

  • shaved northern Italian cow’s milk cheese, like Piave or Montasio, for garnish 

  • Radicchio Orange Mostarda (recipe below)

Radicchio Orange Mostarda
  • 1 orange 

  • 30g (1 oz) extra virgin olive oil 

  • 1 head radicchio, cored and shredded 

  • coarse flaky sea salt 

  • 60g (2 oz) balsamic vinegar 

  • 15g (½ oz) sugar 

  • 15g (½ oz) pickled mustard seeds



  1. Using a sharp knife cut the coulotte in half, against the grain. Wrap in plastic wrap and place in the freezer. Freeze for several hours or overnight until firm.  

  2. When you are ready to slice, remove the meat from the freezer to allow it to temper about 30 minutes before slicing. Using a meat slicer, place the coulotte with the fat cap side up and cut side to the blade. Slice thin-ish slices against the grain, about 0.15cm / 1/16 in thick. You can also use a very sharp long slicing knife to slice the culotte into thin slices. Feel free to play with how thick and thin you go, I recommend, slicing a bit thicker rather than thinner.  

  3. Place the slices flat on parchment paper, careful not to overlap. Each skewer will have 2 slices, so shoot for 24 slices total. Place the slices back in the freezer or fridge to chill if needed. Fold the Wagyu slice in half lengthwise, then thread two slices of Wagyu onto each skewer. Repeat with the remaining skewers. Keep refrigerated until ready to grill. Depending on the size of the culotte, you can slice more than 12 skewers, just keep the meat in the freezer until you are ready for more. 

To Finish

  1. Preheat your grill over high heat. Season the skewers with salt and pepper. Working in batches, place the skewers on the hottest part of your grill, let them cook for 1-1½ minutes per side, allowing them to lightly char on each side. These cook very quickly, so be careful to not overcook. I like to serve them lightly charred and medium rare.  

  2. Remove the skewers to a platter and garnish with a nice drizzle of extra virgin olive oil, dill sprigs and pistachios. Top with a few shavings of Piave cheese. Serve alongside the Radicchio Orange Mostarda. 

Radicchio Orange Mostarda

  1. Using a peeler, peel the orange rind. Using a sharp knife, trim away any white pith from the rinds. Finely julienne the orange rind and set aside. Trim away all the white pith from the orange then use a sharp knife to cut and remove the segments from the membrane. Squeeze the juice from the orange membrane.  

  2. In a medium-sized saucepan, heat the olive oil over medium heat. Add the radicchio to the pan and season with a few pinches of sea salt. Stirring often, allow the radicchio to soften and wilt, about 2 minutes.  

  3. Add the balsamic and sugar and continue to cook down until the syrup has thickened and glazed, about 6-7 minutes.  

  4. Remove the radicchio to a bowl and fold in the orange zest, segments, and pickled mustard seeds. Adjust seasoning with a few generous pinches of salt to taste. Refrigerate the mostarda until ready to use.
