    Slow Cooker Whole Cauliflower Dijon Parmesan is a not-to-be-missed dish. Wholesome cauliflower frosted with a delicious cheesy mustard topping. An easy and wonderful addition to any meal.

    If you haven't already started serving whole roasted cauliflower, you are missing out. It has quickly become my favorite way to serve this perfect vegetable as a side dish or even a main course.

    Bonus: my lazy self is very happy letting everyone carve into a whole head at the table. It certainly beats spending time over the sink cutting it into florets!

    Cauliflower is a definite winner in my house. My most vegetable-adverse child claims it as his favorite. I assume the mild taste and the way it easily adapts to so many different flavors are the reasons.

    Whole slow cooker parmesan cauliflower ingredients with labels

    To make this healthy recipe you will need these wholesome ingredients:

    • Cauliflower - a medium-sized head of cauliflower words perfectly
    • Garlic - minced. Fresh garlic is great. I am lazy and always keep a jar of already minced garlic on hand.
    • Olive oil /
    • Dijon mustard
    • Parmesan cheese - grated (again fresh grated is amazing, but I am too lazy!)

    **Exact quantities and detailed instructions can be found in the recipe card at the bottom of this post.

    🥣Assembly

    Start this cauliflower recipe by rinsing off the head and removing all the leaves. Next, cut the bottom of the head so that it sits flat.

    Insider info: You do not need to use a knife to dig out the full stem of the cauliflower when slow cooking. The low and slow cooking will soften it up and make it just as delicious as the florets.

    In a small bowl, whisk together garlic, olive oil, mustard, and parmesan cheese.

    Grease your slow cooker with a non-stick agent (such as cooking spray or olive oil) of your choice. Place your whole cauliflower head into the bottom of your slow cooker. Use a knife or spatula or spread the mustard-oil mixture all over the head of the cauliflower.

    I like to think of it as similar to frosting a cake. You want to spread a full layer of the parmesan mixture over the entire outside.

    Cover your slow cooker and cook on low for 6-8 hours. Your cauliflower is ready when it is soft at its innermost core. For best results, you can test this by inserting a sharp knife deep into the center.

    🍽Serving suggestions

    To serve this great recipe, just remove it from your slow cooker with tongs and place it on a plate. It can be pulled apart with two forks or cut into thick wedges like a pie.

    For a crispier outer crust, place your cooked cauliflower on a prepared baking sheet. Slide it in the oven on an oven rack and broil. This should take just a few minutes and will brown and crisp things up a bit.

    TOPPINGS

    Sprinkling with some crunchy sesame seeds and fresh parsley is a wonderful way to dress this perfect side dish up. As is melting some freshly grated sharp cheddar cheese on top.

    Some additional topping ideas options include a few grinds of black pepper, some fresh chives, or a sprinkling of your favorite fresh herbs. Lemon wedges are also great served right alongside for anyone who wants a little extra oomph.

    PAIRINGS

    This is one of those easy recipes that goes with just about everything I love serving it with hearty meat dishes such as beef stew and balsamic roast. It is equally great next to a tuna or turkey salad sandwich.

    Storing leftovers

    Leftovers can be easily stored in the refrigerator in an airtight container or bag. They will stay fresh in the fridge for several days and are great eaten cold or quickly reheated in the microwave.

    Leftovers can also be frozen. They are easy to defrost in an oven or microwave. You can freshen things up by topping frozen cauliflower with some fresh parmesan cheese when reheating.

    😉Hints & hacks

    1. Most people would choose to serve their slow cooker whole cauliflower as a side dish. However, it also makes a great main dish. To serve as a main, try cutting it lengthwise into cauliflower steaks. The perfect entree for a non meat eater!
    2. I always recommend the use of a slow cooker liner. This is, of course, an optional step. I like to purchase my liners in bulk for a less expensive per-piece price. 
    3. In the market for a new slow cooker? I love my new one!
    4. This is a great dish if your people will be eating at different times. After the cooking time, turn your slow cooker to low and everyone can grab a chunk of cauliflower, no matter what time they are ready to eat.
    5. Not a fan of slow cooker liners, I just discovered these awesome parchment paper liners that work perfectly with this recipe!
    6. As mentioned, I am a fan of buying minced garlic by the jar. Of course, fresh minced garlic would be a delicious upgrade to this recipe.

    Notes

    Notes:
    ** This recipe calls for "¼+"  of parmesan cheese.  This is meant to indicate that if you are a parmesan lover (like me!) you can feel free to include a heaping ¼ cup of cheese.  
    This dish can be served sliced into steak slices, cut in wedges like a pie, or pulled apart with forks.

      Does 1/4+ cup mean 1 and 1/4 cup?

        Hi Terry, I actually meant a heavy-handed 1/4 cup (not 1 and 1/4). I was trying to indicate that if you love parmesan as much as I do, it's okay to go a little over on that ingredient.
        Thanks for asking and for pointing out that it's a bit confusing. I am going to update the recipe to be more clear.
        Hope you love the cauliflower (I am addicted to it)!!
