Oh, mirror in the sky what is love? Can the child within my heart rise above? Can I sail through the changin’ ocean tides?Can I handle the seasons of my life? ~Stevie Nicks

We loved this simple vegan dinner the other night and thought I’d share. Roasted Cauliflower nestles in flavorful Romesco Sauce over a bed of simmered lentils. It’s a nutritious meal, full of flavor and goodness, that comes together quickly and easily. Truly the place where healthy meets delicious!

What I love about this recipe is how the Romesco Sauce ingredients roast simultaneously as the cauliflower. While baking away in the oven, the lentils are simmering on the stovetop, giving you a little hands-off time before dinner. Then it’s just a matter of whizzing up the flavorful sauce and assembling. A tasty, easy, vegan sheet pan dinner.

Fall has arrived and I’ve been enjoying these brisk temperatures. Something about it makes me feel very alive. When you see the falling of the leaves, the wilting of the flowers, the dying off of nature, it’s a good reminder of how precious this life is. I know it will end, and in a way, I suppose it must, for it to mean something. And then the questions begin to surface, like, have I loved deeply enough? Or dug down far enough within myself to fully experience this life, or shed enough of what is not real? Big sigh…

How to make Roasted Cauliflower with Romesco Sauce

Step one

Preheat the oven and start the lentils cooking on the stovetop. These are the tiny Black caviar lentils that cook in 20 minutes- a lifesaver on busy nights!

slice the cauliflower into steaks

Step two

Slice the Cauliflower into ½-¾ inch slices, then trim the leaves, leaving the stem intact.  Place on a parchment-lined sheet pan that has been sprayed with spray olive oil.

Description

Roasted Cauliflower Steaks with Romesco Sauce over a bed of simply seasoned lentils. A quick and easy sheet pan dinner – vegan, plant-powered, and full of flavor!


Ingredients

Units Scale

Lentils:

  • 1 cup dry lentils (beluga, black caviar lentils, french green lentils, etc- small lentils cook the fastest!)
  • 6 cups water
  • 1 teaspoon salt
  • optional additions: garlic cloves, bay leaves, sliced onion, dried herbs ( thyme, oregano)

garnish: drizzle of olive oil

Sheet Pan:

  • 1 medium cauliflower
  • 1 large bell pepper, halved or quartered
  • 1/2 red onion, sliced
  • 46 fat garlic cloves

Marinade:

Romesco Sauce


Instructions

Preheat oven to 425 F

If making lentils, place water, lentils and salt in a medium pot, bring to a boil, lower heat and simmer gently until tender. See notes for additional seasonings. Drain, drizzle with olive oil.

Sheet Pan:

Spray an extra-large, parchment-lined sheet pan with spray olive oil. ( You may need two if using small pans)

Cut a whole cauliflower into ½-¾ inch slices or “steaks”, and then trim the leaves, leaving the stems. (TIP: leaving the leaves on until after slicing, helps them stay together better while you slice).  Place these on the sheet pan.

Slice the onion into 1/2 inch thick rings and quarter the bell pepper removing seeds and place on the sheet pan, along with the whole garlic cloves.

In a small bowl mix the marinade ingredients together, then brush liberally over the cauliflower, getting the edges too. Brush any remaining over the onion, garlic and bell pepper.

Bake in the oven until the cauliflower steaks are fork-tender and peppers are tender and collapsing, about 35 minutes, checking on the garlic, halfway through. Remove the garlic when golden, ahead of time if need be.

Romesco Sauce: Place the roasted peppers, onion, garlic, and nuts in a food processor and pulse until chopped. Add the salt and spices, tomato paste, vinegar,  olive oil and a little water. Pulse again until well combined, leaving a little texture. Add more water to loosen it and get it saucier- if you like, or keep it thick up to you. Taste and adjust salt and heat level.

Assemble your bowls. Drizzle warm, drained lentils with a little olive oil,  and divide among bowls, spoon romesco sauce on the other side of the lentils, top with a couple of cauliflower steaks.

Scatter with fresh parsley. Enjoy!


Notes

Feel free to season the lentils with any additional aromatics:  adding garlic clove, dried herbs, bay leaves, to the cooking liquid.

Leftovers can be reheated (baked). If reheating the romesco sauce, stir in another tablespoon of water to prevent it from drying out.

  1. Just a note to ask, aren’t the roasted red bells missing from the ingredient list in the romesco sauce ingredients? Mentioned in the instructions, but I think missing from the list?

    1. Hi Michele, it is listed under the “Sheet Pan” heading. Easy to miss. 🙂

      1. Thanks! I reread three times before I saw it there. Duh to me! 🙂 Thanks for the always wonderful recipes.

  2. This is unbelievable good!! I doubled the marinade so I’d have good coverage. What a delicious dinner!

  3. Loved this recipe! I recommend doubling the Romesco sauce, it was so tasty I wanted to add it to other meals 🙂

  4. This was amazing! I had never tasted romesco sauce before and wasn’t sure about adding almonds, but it was delicious. I sautéed zucchini as a side and it also tasted great with the romesco sauce. Thanks for sharing this amazing recipe!

  5. Made this tonight. So-o-o-o flavourful, delicious and balanced!!! Ohhh, that sauce…yummy. I can imagine it on other proteins. Since you suggested toasted hazelnuts as an alt for Marcona almonds, I used whole blanched almonds and lightly toasted them to bring out their flavour. That seemed to work really well.
    Thanks for all your terrific, inspiring recipes.

  6. Absolutely brilliant! Our vegan friend was very happy with it too, and the leftovers we had on the second day were perhaps even better. Thank you do much for your gorgeous recipes 🙂

  7. This meal is a new favorite in our house – Thank you! Happy to have stumbled onto your blog – can’t wait to try more recipes from you!

  8. This was delicious and so easy. I love a sheet pan meal and this one is exceptional. Just two of us so I cut the Cauliflower in half but may make the other half later this week it was so good.
