Mizuna & Walnut Pesto Crostini

Crostini are addicting little toasts.  Mizuna is a Japanese plant similar in taste to Arugula and also in the same family: the mustard or Brassicaceae family.  Don’t want to make the pesto?  No problem – buy some store bought pesto and skip that step.

Ingredient List Crostini:

  • 1 large baguette, sliced 1/4″ thick on the diagonal
  • e.v. olive oil
  • 1/4 cup Parmesan Cheese – for garnish

Ingredient List Pesto:

  • 1 cup Walnuts, toasted
  • 4 cups (~ 6 ounces) Mizuna
  • 1/2 cup e.v. olive oil
  • 1/2 cup Parmesan Cheese, grated
  • 1 Tbsp garlic, minced & sauteed
  • 2 lemons, zested
  • 3 Tbsp fresh lemon juice
  • 1/4 tsp sea salt
  • 1/4 tsp black pepper


  • Preheat the oven to 350F.
  • Line a sheet with aluminum foil and toast 1 cup Walnuts (any nut will work if you don’t have walnuts) at 350F for ~ 6-8 minutes uncovered.  The nuts should be fragrant and hot when you take them out of the oven.  Set aside to cool. Keep aluminum on tray to toast the bread
  • Slice one large baguette on the diagonal (you should get ~30-35 pieces).   Baste each side of every slice with a little e.v. olive oil.  Lightly sea salt and pepper one or both sides.  Bake at 350F ~ 8- 10 minutes uncovered.  You want these guys to be crispy but not burnt.  Some people say toast until golden, but they’ve gone too long if they start changing to a darker color.  After all, you want the roof of your mouth to stay intact!
  • Bring a pan to medium high heat and add the garlic.  Cook ~ 1-2 minutes or until the garlic is fragrant.
  • Zest 2 large lemons.  Set zest aside and juice lemons.
  • Make the pesto:  In a food processor add: walnuts, Mizuna, 1/2 cup of the Parmesan cheese (reserving the rest for garnish), garlic, lemon juice, sea salt, and black pepper.  Slowly add in the olive oil while “whizzing” it up.  Substitute or add a little water if you want a thinner consistency or are trying to cut down on the oil.  Add sea salt and e.v. olive oil to taste to the pesto, but remember that the crostini have salt on them already.
  • Spread the pesto over the crostini and top with a touch of grated Parmesan Cheese and lemon zest.  Happy Eating!  Beckie


  • You can make the crostini up to one day ahead of time and store in a ziploc bag overnight.
  • Can’t find mizuna?  Use Arugula instead.
  • Cutting on the diagonal will give you more surface area for the topping (plus look cooler!)
  • Don’t want to dirty a pan just for garlic?  Skip cooking the garlic and use it in the pesto raw.


Things In My Kitchen:

  • Microplane Zester – for zesting the lemon.
  • Food Processor – for making pesto.  My favorite is an 11 cup, but it’s often to big for pesto.  A 7 or 8 cup is a nice alternative if you want something smaller.
