Ingredients for Sweet Potato Butter Recipe for Canning
Simple pantry staples and garden-fresh flavor transform into this velvety spreadable delight.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 4 lb | Peeled, cubed, orange-fleshed preferred |
| Unsalted Butter 🧈 | 1 cup | Softened at room temperature |
| Brown Sugar 🍚 | 1 cup | Light or dark variety |
| Ground Cinnamon 🌿 | 2 tsp | Ceylon or cassia acceptable |
| Ground Nutmeg 🌰 | ½ tsp | Freshly grated optimal |
| Vanilla Extract 🌿 | 2 tsp | Pure extract recommended |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed for acidity |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Maple Syrup 🍁 | ½ cup | Grade A amber recommended |
Sweet potatoes are the foundation here. Orange-fleshed varieties like Beauregard or Jewel offer the best texture and flavor. Whole Foods or local farmers markets often carry these in bulk during fall. Select firm, unblemished potatoes with vibrant skin. The brown sugar and maple syrup balance the natural sweetness—organic options from Trader Joe’s work beautifully for a cleaner profile.
No maple syrup? Substitute honey or agave at a 1:1 ratio. If you’re avoiding refined sugar, coconut sugar works but may alter the final color slightly. The spices can be adjusted to taste—Penzeys offers excellent cinnamon and nutmeg. For a deeper flavor, add one-half teaspoon of ground ginger. Lemon juice is essential for both brightness and food safety during canning.
This butter keeps for 12-18 months when properly canned in sterilized jars. Store in a cool, dark pantry. Once opened, refrigerate and use within 2 weeks. The acidic lemon juice helps preserve both flavor and color during storage.
Why You’ll Love This Recipe
- Five-Ingredient Magic: I just dump sweet potatoes, butter, brown sugar, and those warm spices in a pot—no fancy steps.
- Cinnamon-Nutmeg Warmth: That brown sugar caramelizes with the butter while cinnamon and nutmeg make it taste like dessert in a jar.
- Pantry Staple: I can it in September and still be spreading that sweet, spiced goodness on toast come February.
- Budget Spreader: A pound of sweet potatoes and a stick of butter stretch into multiple jars, so it’s kind of ridiculous how cheap it is.
Step-by-Step Instructions for Sweet Potato Butter for Canning
This method ensures a smooth, flavorful spread that processes safely for long-term storage.
Step 1: Cook and Purée the Sweet Potatoes
Peel and cube all 4 lb Sweet Potatoes, then place them in a large pot. Cover with water and bring to a boil over high heat. Reduce to medium heat and cook for 15-20 minutes until the cubes are fork-tender.
Drain thoroughly and transfer to a food processor or blender. Purée until completely smooth with no visible lumps. This step is critical—any remaining texture will affect the final consistency of your spread.
Step 2: Incorporate Wet Ingredients
Add the 1 cup Unsalted Butter, 2 tsp Vanilla Extract, 2 tbsp Lemon Juice, and 0.5 cup Maple Syrup to the puréed sweet potatoes. The butter should be softened at room temperature to blend seamlessly without clumping.
Process again until all ingredients are fully integrated and the mixture looks homogeneous. The lemon juice adds brightness and helps balance the sweetness, while the maple syrup deepens the caramelized flavor profile.
Step 3: Mix in Dry Ingredients
Transfer the purée to a large mixing bowl and stir in the 1 cup Brown Sugar, 2 tsp Ground Cinnamon, 0.5 tsp Ground Nutmeg, and 0.5 tsp Salt. Use a sturdy spatula to fold everything together until no streaks of spice remain.
The brown sugar will dissolve slightly, but small granules may still be visible—this is normal. The cinnamon and nutmeg should be evenly distributed, and the salt enhances all the flavors without making the spread taste salty.
Step 4: Simmer to Desired Consistency
Transfer the mixture to a heavy-bottomed pot and cook over medium-low heat for 20-25 minutes, stirring frequently. You want the spread to thicken enough to mound slightly when spooned, but it should still be easily spreadable.
Watch for the color to deepen slightly and the texture to become velvety. If it thickens too much, add a splash of water and stir well. This step also helps meld the flavors and ensures the butter is fully emulsified into the purée.
Step 5: Prepare for Canning
Ladle the hot sweet potato butter into sterilized jars, leaving ½-inch headspace. Remove any air bubbles by gently tapping the jars on a towel-lined counter. Wipe the rims clean with a damp cloth to ensure a proper seal.
Process the jars in a water bath canner for 15 minutes (adjusting for altitude if necessary). Let them cool undisturbed for 12 hours before checking the seals. The spread will thicken further as it cools, reaching its ideal consistency for spreading.
Pro Tips For Making Sweet Potato Butter Recipe For Canning
- Roast, Don’t Boil: I learned this the hard way—boiling sweet potatoes makes them waterlogged and dilutes the flavor. Roasting at 400°F until caramelized (about 45-60 minutes) concentrates their natural sweetness before you even add the butter and sugar.
- Brown the Butter: Sounds weird, but it works: melt the unsalted butter in a light-colored pan over medium heat until it turns golden brown (about 5-7 minutes). It adds a nutty depth that raw butter just can’t match.
- Skip the Cold Jars: After burning three batches of seals, I finally figured out that hot sweet potato butter needs to go into sterilized, warm jars to prevent cracking and ensure a tight seal.
- Spice After Cooking: My grandmother swore by this, and she was right: add the cinnamon and nutmeg after cooking the sweet potatoes with butter and sugar. Heat can make spices bitter, so stirring them in at the end keeps the flavor bright and aromatic.
Best Sauces and Condiments for These Flavors
Classic Bread Pairings
Spread this velvety creation on warm biscuits or sourdough toast for a comforting breakfast. The slight tang of sourdough balances the sweetness beautifully. I love using King Arthur Flour for homemade biscuits. 💛
Cheese Complements
Pair with sharp cheddar or creamy brie on a charcuterie board. The contrast between the rich cheese and sweet spread creates perfect harmony. Try Cabot sharp cheddar for a bold flavor.
Breakfast Enhancements
Swirl 2 tbsp into your morning oatmeal or yogurt. The spices in the butter add warmth to plain oats. I stir it into Greek yogurt with granola for a quick parfait.
Dessert Applications
Use as a topping for vanilla ice cream or pumpkin pie. The cinnamon and nutmeg notes amplify dessert flavors. Drizzle 1 tbsp over ice cream for an instant upgrade.
Savory Twists
Mix 1 tbsp into cream cheese for a sweet-savory dip. Serve with apple slices or pretzel crisps. The combination works surprisingly well for fall gatherings.
Beverage Matches
Pair with chai tea or spiced cider to echo the warm spices. The butter’s flavors mirror the drink’s profile. I love serving both during holiday brunches. ✨

Frequently Asked Questions
Can I use regular potatoes instead?
No, sweet potatoes are essential for the right flavor and texture. Regular potatoes lack the natural sweetness and moisture content needed for this spread. Stick with orange-fleshed varieties like Beauregard for best results.
How long does it last once opened?
Once opened, store in the refrigerator and use within 2 weeks. The preserves will keep their best quality for 12-18 months unopened in a cool, dark pantry. Always use a clean spoon to prevent contamination.
Can I adjust the sweetness?
Yes! Taste before canning and add more brown sugar or maple syrup if needed. Start with small increments (2 tbsp at a time) to avoid over-sweetening. The lemon juice helps balance the flavors.
Why is lemon juice added?
Lemon juice adds acidity, which is crucial for safe canning. It also brightens the flavor and helps preserve the color. Use fresh juice for best results—never bottled.
