We eat a lot more pasta at this house than you might guess from just looking at this blog. Like at least once a week. And yet, this post is one of only two devoted to that starchy comfort that easily loans itself to pantry-cooking. I usually stock some type of spelt/whole grain noodle or brown rice penne in my little grain/cereal drawer. One of those two options with red sauce is both my man’s and my own comfort food of choice. If we’re having pasta for a nicer mid-week dinner though, I’ll be doing a light olive oil-based sauce with cooked vegetables, chickpeas, pine nut parm, greens etc., just to make it more special.

A little while ago, I received a copy of a new book from America’s Test Kitchen: The Complete Vegetarian Cookbook. The anticipation over a plant-based collection from ATK was evident when I excitedly ripped the packing envelope one snowy afternoon. As I flipped through chapters focusing on hearty mains, soups, pasta + noodles, rice, grains, sides, salads, beans + soy, snacks, flatbreads, and more, I noticed a lot of the recipes that were jumping out at me were mostly comprised of items I already had in my pantry. I love when vegetarian recipes focus on building flavour with accessible, everyday ingredients, and this book really seems to understand that.

So onto today’s recipe… I chose this one because I had a giant head of cauliflower in the fridge and a pasta with that and roasted garlic sounded too cozy to pass on. We’re in a proper cold snap and it called to me from the page. I made a few minor changes (omitted the parmesan, subbed arugula for parsley), but kept the lightly sweet and full-flavoured roasted garlic and lemon sauce completely intact. I honestly can’t wait to make it again. You just mash some roasted garlic cloves with olive oil, lemon and chili flakes, thin the mixture out with starchy pasta water, and toss it with hot pasta and roasted cauliflower.

roasted garlic + cauliflower pasta with walnuts (vegan + gluten-free)
Servings 4

Ingredients

  • 2 heads garlic, top quarter cut off to expose cloves
  • 6 tablespoons + 1 teaspoon olive oil
  • ½ pinchteaspoon fresh thyme leaves
  • 1 head cauliflower (2 lbs)
  • sea salt and ground black pepper to taste
  • 2 tablespoons lemon juice, plus extra
  • 1/4 teaspoon red pepper flakes, or to taste
  • 1 lb short brown rice pasta, such as penne or fusilli
  • 2-3 handfuls baby arugula
  • 1/4 cup walnut halves, toasted and chopped

Notes

  • From America’s Test Kitchen’s The Complete Vegetarian Cookbook
  • ATK lists an alternative version of this pasta with broccoli and almonds as well if that catches your interest. The original recipe calls for chopped parsley, but I used handfuls of baby arugula because I happened to have it in my fridge.

Instructions

  • Adjust an oven rack to the middle position, place a naked baking sheet on the rack and preheat to 500°F. Tear two squares of aluminum foil and place cut garlic heads in the centers. Drizzle exposed garlic tops with 1/2 tsp olive oil each. Season with salt, pepper, and thyme leaves (if using). Wrap garlic bulbs up securely and place in the oven. Roast until garlic is browned and mushy/tender, about 40 minutes.
  • While garlic is roasting, trim the cauliflower leaves and the extra bit of stalk at the bottom. Cut the head right down the middle, from top to bottom. From there, cut each half into 4 wedges. In a medium bowl, toss the cauliflower wedges with 2 tablespoons olive oil, salt, and pepper. Remove the pre-heated baking sheet from the oven and carefully lay the cauliflower wedges onto the surface, leaving some space around each piece. You should hear sizzling. Roast cauliflower until tender and well-browned, about 25 minutes (I flipped mine halfway).
  • Once slightly cooled, transfer cauliflower to a cutting board and cut into bite-size pieces. Unwrap roasted garlic and squeeze cloves out into a small bowl. Mash roasted garlic with a fork to make a smooth puree. Whisk in the lemon juice, pepper flakes, some salt + pepper, and 1/4 cup of olive oil. Set aside.
  • Cook brown rice pasta according to package directions with a fat pinch of salt in the water. Reserve 1 cup of pasta cooking water before draining. Once drained, return cooked pasta to the pot. Add chopped cauliflower, garlic sauce, arugula, extra lemon juice to taste, and 1/4 cup reserved cooking water. Add more cooking water as necessary to achieve desired consistency. Serve pasta with handfuls of chopped walnuts on top and extra chili flakes.

  • coral

    brown basmati rice, butternut squash, mushrooms, warming spices, and a cuisinart – all serve to make vegetarian fare more hearty or filling which is a requirement for my husband!

  • Jessica DeMarra

    I love America’s Test Kitchen! I currently own three of their books and quite the stack of their magazines. I love the food science aspect of it and it is what got me into cooking. I am so glad they are coming out with a plant-based book! My top five pantry staples are: Utopia organic canned tomatoes, dried lentils/chickpeas, liquid braggs, chia seeds and black rice noodles. I can’t wait until this book comes out to see all of their recipe ideas and taste profiling! Even if I don’t win, I will purchasing a copy. What a great giveaway!

  • ame

    lentils, tahini, nuts, sh-t loads of veggies, spices!

  • Charity

    For vegan meals (and any meal, really) I always try to have on hand:
    1. Fresh basil
    2. Onion
    3. Fresh garlic
    4. Good olive oil
    5. Whole black peppercorns.

    I think you can do just about anything with those 5 things as a jumping off point. :-)

  • Teresa Cochran

    Garbanzo beans
    Olive oil
    canned tomatoes
    garlic
    onions

  • Sandra elliott

    Raw nuts
    Coconut milk
    Coconut oil
    Quinoa
    Avocado

  • Kathy Sturr

    This looks so delicious! I am really into cauliflower right now. My husband and I have roasted whole cauliflowers for a snack. Cauliflower is so delicious! I always keep vegetables on hand especially cauliflower, broccoli, kale, onion, garlic. But what I MUST have in my pantry (because there’s no going around the corner to pick up some in a pinch) is tempeh, tofu, raw cashews, nutritional yeast, and coconut milk. I am a vegetarian extremist – vegan! Can’t wait to try this recipe. Love your beautiful delicious photography, too.

  • aryss

    I always keep tomato paste, dried beans, tofu, almond butter, and baby spinach on hand!

  • krystal

    I’ve always got nuts, beans, quinoa, oats, and some kind of canned tomatoes on hand.

  • Maria Anne

    I always have onions, garlic, brown rice, chickpeas and at least one green vegetable at all times! I have a problem of over-stocking for the week and then not knowing where to start, actually! I love making stuff up out of what I have available and being pleasantly surprised when the meal turns out well!

    Vegetarian ingredients I rely on are pulses such as lentils, navy beans, peas, & limas; fats such as olive & coconut oils; nuts & seeds and their butters, squashes for healthy digestible starches; fresh & dried seasonings like ginger, garlic, herbs & spices. I am not vegetarian and following a GAPS type diet to heal some digestive issues.

  • Ashley

  • Naadia

    I’m still learning to cook and I wouldn’t say I have pantry staples or enough go-to recipes yet. If I had to pick five things, I’d say probably pasta, quinoa, diced tomatoes, chickpeas and tofu. Definitely too much tofu–I’m frequently guilty of throwing sauce on a block of tofu and calling that a meal. I’m working on diversifying my diet and it’s helpful/interesting to read all the different responses to this question!

    PS where do you find fire roasted tomatoes?! I’ve never seen them, I just assumed they were an American thing.

    • Laura Wright

      Hey Naadia! I live right by a US/Canada border, so I trek over to the USA for them every once in a while.

  • Lane | Green Spirit Adventures

    This recipe is stunning! (As are the photos!) I can’t wait to give it a try. Roasted cauliflower is one of my favorite wintery comfort foods and I’ve actually just recently tried brown rice pasta – after several years of not being able to eat white pasta. It’s so delicious and I don’t miss white pasta at all!
    I always try to keep plenty of greens stocked in my kitchen (especially kale or chard), lemons, tahini and/or almond butter, coconut oil, and dried lentils, chickpeas or quinoa.
