This is a baked mac and cheese with a cashew-cream base and Frank’s RedHot stirred through the sauce, finished with a buttered panko crust. It comes together in about 45 minutes and feeds a crowd without requiring anything exotic. The cashew sauce pulls real protein duty here, so this casserole is a lot more filling than it looks.
Smart swaps
- Raw cashews: These are the base of the cheese sauce, so don’t skip them. If you can’t find raw cashews, raw sunflower seeds work and blend just as smooth after soaking — the flavor is slightly earthier but still good.
- Nutritional yeast: Sold in most grocery stores near the health foods. It’s not optional here — it’s where most of the cheesy flavor comes from.
- Tapioca starch: This is what gives the sauce its stretch. Arrowroot powder is a direct swap in equal amounts. Cornstarch will thicken the sauce but won’t give you the same pull.
- Frank’s RedHot: Other cayenne-based hot sauces work. Avoid sriracha or chipotle sauces — they’ll change the flavor profile significantly.
- Vegan butter: Any stick-style vegan butter works for both the sauce and the panko topping. Avoid spread-style products with high water content — they can make the topping soggy.
- White miso: Adds background umami. Yellow miso is a fine substitute. Skip red miso — it’s too strong and will overpower the hot sauce.
Why this recipe works
Two things actually matter here. First, the tapioca starch is activated by simmering the blended cashew sauce before it goes anywhere near the pasta — this step is what turns a thin liquid into a glossy, coating sauce rather than something that pools at the bottom of the dish. Second, the pasta goes into the baking dish slightly undercooked on purpose. It finishes in the oven while absorbing the sauce, which means the final texture is creamy all the way through rather than having a dry, separated layer under the crust. Both steps are easy to rush, and both are worth doing properly.
Common problems and fixes
- Sauce is grainy after blending: The cashews weren’t soft enough. Blend for a full two minutes and, if it’s still gritty, strain through a fine mesh sieve before simmering. A high-speed blender helps a lot here.
- Casserole is dry after baking: The pasta was cooked too long before baking, or the dish went in uncovered for the full time. Cover with foil for the first two-thirds of baking, then uncover to brown the top.
- Panko topping is pale and soft: The vegan butter wasn’t fully worked into the breadcrumbs, or the oven wasn’t hot enough. Make sure every crumb is coated and the oven is fully preheated before the dish goes in.
- Sauce tastes flat: Hot sauce and nutritional yeast both need salt to bloom. Taste the sauce before combining it with the pasta and adjust — it should taste slightly over-seasoned at that stage.
- Too spicy for some guests: Reduce the hot sauce by half and serve extra on the side. The sauce base is mild on its own, so this is easy to dial back without rebuilding the recipe.
Storage and reheating
Leftovers keep in an airtight container in the fridge for up to four days. The sauce thickens considerably once cold — add a splash of plain plant-based milk or water before reheating to loosen it. Reheat individual portions in the microwave in 90-second intervals, stirring between each, or warm the whole dish covered in a 350°F oven for about 20 minutes. Skip the garnish when reheating — not worth the extra dish. This recipe freezes reasonably well for up to six weeks; freeze in portions before adding the panko topping, then add fresh breadcrumbs and bake from thawed.

- 1 tablespoon fresh chives finely chopped, for garnish; optional
Instructions
- Prep and Preheat: Heat the oven to 400°F (200°C). Lightly grease a 9x13-inch (3-qt) baking dish with 1 teaspoon avocado oil. Set a large pot of water to boil and season it with 1 tablespoon kosher salt.
- Quick-Soak the Cashews (15 minutes): Place 1 cup raw cashews in a heatproof bowl and cover with boiling water. Soak for 15 minutes to soften. Drain before blending. (If you have time, an overnight cold soak yields an ultra-silky sauce.)
- Cook the Pasta (6–7 minutes): Add 12 oz elbow macaroni to the boiling water and cook until very al dente—about 6–7 minutes. The pasta should still have a firm core, as it will finish in the oven. Drain well.
- Blend the Buffalo Cashew Cream (1–2 minutes): In a high-speed blender, combine drained cashews, 1/2 cup hot sauce, 1 cup oat milk, 1/2 cup vegetable broth, 3 tbsp melted vegan butter, 1/4 cup nutritional yeast, 1 tbsp white miso, 1 tbsp lemon juice, 1 tsp apple cider vinegar, 3 garlic cloves, 1 tsp onion powder, 1/2 tsp smoked paprika, 1/2 tsp ground mustard, 1 tsp kosher salt, 1/2 tsp black pepper, and 1 tbsp tapioca starch. Blend on high until completely smooth and glossy, 60–90 seconds. Sensory cue: the sauce should look velvety with no visible grain.
- Simmer to Activate (5 minutes): Pour the blended sauce into a medium saucepan over medium heat. Bring to a gentle simmer and whisk for 3–5 minutes until slightly thickened and shiny; it should coat the back of a spoon. Reduce heat if it threatens to boil over—gentle bubbles are ideal.
- Combine and Pan: In a large bowl, fold the hot pasta with the warm Buffalo cream, 1 cup vegan mozzarella shreds, the diced celery, and half the sliced scallions. Toss until every elbow is well coated and the cheese begins to soften. Transfer the mixture to the prepared baking dish, smoothing the top with a spatula.
- Make the Crispy Topping: In a bowl, mix 1 cup panko, 2 tbsp melted vegan butter, 1/2 tsp garlic powder, 1 tsp dried parsley, and 1/4 tsp kosher salt until evenly moistened. Sprinkle the crumbs in an even layer over the pasta.
- Bake (15 minutes at 400°F/200°C): Bake until the edges are bubbling like molten lava and the topping is pale golden, about 15 minutes. Optional: For deeper color, broil on high for 1–2 minutes at 500°F (260°C)—watch closely. (Broil time not included in the stated cook time.)
- Finish and Serve: Let the bake rest 5 minutes so the sauce settles. Drizzle with vegan ranch, then scatter remaining scallions and the chives. Serve immediately while steamy and crisp on top.
- Storage: Refrigerate leftovers in an airtight container for up to 3 days. Reheat covered at 350°F (175°C) until hot, then uncover for 3–5 minutes to re-crisp.
Notes
Michelle’s Tips:
- Dial the Heat: For milder heat, reduce hot sauce to 1/3 cup and add 1–2 teaspoons maple syrup to soften the edges. For extra fire, stir in 1/4–1/2 teaspoon cayenne.
- Cheesier Pull: Add 2–3 tablespoons more tapioca starch for extra stretch, or fold in 2 ounces vegan cream cheese with the mozzarella.
- Gluten-Free: Use gluten-free elbows and gluten-free panko. Bake time remains the same, but undercook the pasta by an extra minute to avoid mushiness.
- Nut-Free: Substitute 14 ounces silken tofu for the cashews (no soak needed). Add 1 tablespoon olive oil and 1 extra tablespoon nutritional yeast for richness.
- Oil-Free Path: Omit vegan butter; replace with 3 tablespoons aquafaba in the sauce and toss panko with 1 tablespoon aquafaba. Topping will be lighter but still crisp.
- Topping Texture: For ultra-crunch, pre-toast panko in a dry skillet over medium heat for 2–3 minutes, stirring constantly, just until blond—then mix with melted butter and seasonings. Watch closely; it colors fast.
- No Blender? A food processor works; scrape down often. For silkiest results, pass the sauce through a fine-mesh sieve before simmering.
- Season Like a Pro: After simmering, taste the sauce. If it feels flat, add a splash of lemon for brightness or a pinch more salt to pop the Buffalo tang.
Serving Suggestions:
- Plating: Spoon into warm, shallow bowls so the sauce stays glossy. Drizzle a lazy zigzag of vegan ranch and finish with a confetti of scallion greens and chives.
- Color & Aroma: Look for a pale golden topping with darker toasted freckles, lava-like bubbling at the edges, and the unmistakable aroma of buttery hot sauce and garlic.
- Sides & Sips: Pair with a crisp celery–apple slaw and lemony vinaigrette. Drink with a chilled pilsner, a hoppy IPA, or a tart ginger kombucha.
Culinary Context:
Buffalo sauce was born in Buffalo, NY—typically a mix of cayenne hot sauce and butter, tossed with fried wings. This vegan bake captures that craveable tang and heat, then marries it with the comfort of mac and cheese—no dairy, no compromise. I first built this for a playoff party; it outshone every dip on the table.Optional Advanced Instructions:
- Make-Ahead: Assemble up to 24 hours in advance. Cover and refrigerate. Bake covered at 400°F (200°C) for 20 minutes, uncover, then bake 10 more minutes to re-crisp.
- Freeze: Wrap unbaked casserole tightly and freeze up to 1 month. Bake from frozen at 375°F (190°C) covered for 35 minutes, then uncover and bake 15–20 minutes more. Add ranch and herbs after baking.
- Parallel Workflow: Soak cashews while you preheat and chop; simmer the sauce while the pasta drains; mix the topping while the casserole is being assembled.

Your questions, answered
Do I have to soak the cashews, or can I skip it?
You need to soak them — dry cashews won’t blend smooth enough to make a creamy sauce. The quick-soak method in boiling water for 20–30 minutes works fine if you don’t have time to soak them overnight.
Is this recipe high in protein?
It’s a solid source. Cashews, nutritional yeast, and miso all contribute protein, and a standard serving lands in a similar range to a bean-based dish. If you want to push the protein further, stir a cup of cooked white beans or drained chickpeas into the pasta before baking — they disappear into the sauce and add about 7–8 grams per serving.
Can I make this gluten-free?
Yes. Use a gluten-free pasta and swap the panko for certified gluten-free breadcrumbs or crushed rice crackers. Also check your miso label — most white miso is gluten-free, but some brands use barley.
Can I assemble this ahead of time?
Yes — assemble the full casserole, cover it tightly, and refrigerate for up to 24 hours before baking. Add the panko topping right before it goes into the oven so it doesn’t absorb moisture and go soft overnight.
My family doesn’t like spicy food. Will this still taste good with less hot sauce?
It will. The cashew sauce has good flavor on its own from the nutritional yeast and miso, and the hot sauce is adjustable without breaking anything. Start with a quarter of the called-for amount and taste as you go.
What can I serve alongside this to make it a full meal?
A simple green salad or raw celery and carrot sticks work well and cut through the richness. If you want something more substantial, a side of steamed edamame or roasted chickpeas adds protein and takes almost no effort.
