What Ingredients You Will Need

This creamy paleo loaded cauliflower casserole combines simple, wholesome ingredients to create bold flavors and satisfying textures without fuss. Most are kitchen staples or easy to find at your local grocery or health food store.

For the Casserole Base:

• 1 large head of cauliflower, chopped into florets (about 6 cups) – choose firm, fresh heads for best texture
• 6 slices of thick-cut bacon, chopped (adds a smoky crunch)
• 1 small yellow onion, finely diced (for sweetness and depth)
• 3 cloves garlic, minced (aroma and flavor foundation)

For the Cashew Cream Sauce:

• 1 cup raw cashews, soaked in hot water for at least 20 minutes (creates the creamy base)
• 1 cup unsweetened almond milk (or any paleo-friendly plant milk)
• 2 tablespoons nutritional yeast (adds cheesy flavor without dairy)
• 1 tablespoon lemon juice (brightens the sauce)
• 1 teaspoon Dijon mustard (depth and tang)
• Salt and freshly ground black pepper, to taste

For the Topping:

• 1/2 cup paleo-friendly shredded cheese alternative (optional, for extra melty topping)
• 2 tablespoons fresh chives or parsley, chopped (for freshness)

Ingredient notes: I personally like using *365 by Whole Foods Market* almond milk for its neutral flavor, and *Primal Kitchen* bacon for a clean, smoky punch. If you want a dairy-free version without cheese, just leave it out—the casserole is rich enough on its own. For a gluten-free or nut-free swap, sunflower seeds blended with coconut milk can replace cashews, but the texture will be slightly different.

Equipment Needed

• Large pot or steamer basket: To steam cauliflower until tender but not mushy.
• High-speed blender or food processor: Essential for making the smooth cashew cream sauce. I’ve tried with a regular blender, but it takes longer and can leave bits behind.
• Large skillet: For cooking bacon and sautéing onions and garlic.
• 9×13-inch baking dish: A standard size that fits this recipe perfectly.
• Mixing bowls and utensils: For combining ingredients and prepping.

If you don’t have a steamer basket, no worries—just boil the cauliflower briefly, but keep a close eye so it doesn’t get too soft. For the blender, if you only have a less powerful model, soak the cashews longer (up to 2 hours) to help with creaminess. I’ve found that investing in a good quality blender really pays off for dishes like this one.

Preparation Method

1. Preheat your oven to 375°F (190°C). This gives everything a chance to warm while you prep.
2. Steam the cauliflower florets: Place them in a steamer basket over boiling water, cover, and steam for 8-10 minutes until tender but still firm. You want them soft enough to mash slightly but not falling apart.
3. Cook the bacon: In a large skillet over medium heat, cook chopped bacon until crispy, about 6-8 minutes. Use a slotted spoon to remove bacon pieces and drain on paper towels, reserving about 1 tablespoon of bacon fat in the pan.
4. Sauté onions and garlic: Add diced onions to the bacon fat and cook until translucent, about 5 minutes. Stir in garlic and cook for another minute until fragrant. Remove from heat.
5. Make the cashew cream sauce: Drain soaked cashews and add them to a blender with almond milk, nutritional yeast, lemon juice, Dijon mustard, salt, and pepper. Blend on high until completely smooth and creamy, scraping down sides as needed (about 1-2 minutes). The sauce should coat the back of a spoon.
6. Combine everything: In a large mixing bowl, gently toss steamed cauliflower, sautéed onions and garlic, crispy bacon, and cashew cream sauce until evenly coated. Taste and adjust seasoning if necessary.
7. Transfer to baking dish: Pour the mixture into your prepared 9×13-inch dish, spreading it out evenly. Sprinkle shredded paleo cheese alternative over the top if using.
8. Bake: Place the casserole in the oven and bake for 20-25 minutes until the top is golden and bubbly. The edges should bubble slightly, and the cheese substitute will melt beautifully.
9. Garnish and serve: Remove from oven, sprinkle with fresh chives or parsley for a pop of color and fresh flavor. Let it cool for 5 minutes before serving.

Pro tip: If the sauce seems too thick when blending, add a splash more almond milk rather than water—that keeps the flavor rich. Also, watch the cauliflower carefully during steaming; undercooked florets can give a raw texture, while overcooked ones turn mushy and watery.

Cooking Tips & Techniques

Making this creamy paleo loaded cauliflower casserole is all about balance and timing. Here are some tips I’ve picked up from multiple batches (some more successful than others!):

• Don’t skip soaking the cashews: It’s tempting to blend dry nuts, but soaking softens them for a smoother, silkier sauce that feels truly creamy.
• Steam, don’t boil: Steaming keeps cauliflower firm and prevents it from absorbing too much water, which can dilute the sauce.
• Cook bacon first: This renders the fat needed for sautéing onions and garlic, layering the casserole with subtle smoky undertones.
• Season in layers: Salt the cauliflower lightly before steaming, then adjust salt in the sauce—this prevents bland bites.
• Use fresh garlic and onion: Their sweetness and pungency make all the difference in flavor depth.
• Give the casserole time to rest: Letting it sit for a few minutes after baking helps the sauce thicken slightly, making serving easier and flavors more pronounced.

One time I tried leaving out the Dijon mustard from the sauce, and honestly, it missed that subtle tang that balances the creaminess. So don’t skip it! Also, multitask by prepping the sauce while your cauliflower steams—that saves precious minutes on busy nights.

Variations & Adaptations

This casserole lends itself well to tweaks for different diets, tastes, or seasonal availability.

• Vegetarian version: Skip bacon and add sautéed mushrooms or caramelized onions for umami richness.
• Nut-free option: Replace cashews with soaked sunflower seeds blended with coconut milk—texture changes slightly but still creamy.
• Spicy twist: Add a pinch of smoked paprika or a dash of cayenne to the sauce for warmth and depth.
• Seasonal veggie swap: In summer, swap half the cauliflower for chopped zucchini or fresh green beans for a lighter feel.
• Different cooking method: Try making this in an air fryer-safe dish for faster cooking and crisper edges.

Personally, I once added roasted garlic instead of raw minced garlic for a mellow, sweet flavor that paired beautifully with the sauce. It was a nice change when I wanted something a bit softer in taste but just as comforting.

Serving & Storage Suggestions

This creamy paleo loaded cauliflower casserole is best served warm, right out of the oven. The melty, golden topping and fresh herbs make it visually inviting and ready to eat.

Pair it with a crisp green salad or roasted chicken for a full meal. It also works well alongside sautéed greens or roasted root vegetables for a hearty, veggie-packed dinner.

To store, place leftovers in an airtight container and refrigerate for up to 3 days. The casserole reheats well in the oven at 350°F (175°C) for about 15 minutes or until warmed through. You can also microwave individual portions, but the oven method helps maintain that casserole texture.

Flavors tend to deepen after a day or two, making leftovers even more satisfying. If you want to freeze it, do so before baking—wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and bake as directed.
