How to Make Pumpkin Seed Butter the Right Way
A nutrient-dense, vegan spread that supports digestion and enhances bioavailability.
Making pumpkin seed butter correctly is key to unlocking its full nutritional potential. The process begins with soaking the seeds, a crucial step that activates enzymes and reduces anti-nutrients such as phytic acid. This not only improves digestion but also enhances the bioavailability of essential minerals like zinc, magnesium, and iron.
Step-by-Step Guide:
Soak the Seeds: Place raw pumpkin seeds in filtered water and soak for 6–8 hours (or overnight). This helps neutralize enzyme inhibitors and prepares the seeds for optimal nutrient absorption.
Dry and Roast: After soaking, thoroughly rinse and pat dry the seeds. Spread them on a baking tray and roast at a low temperature—160°C (320°F)—for 8–10 minutes, just until they’re dry and lightly toasted. This gentle heat preserves healthy fats while enhancing flavor.
Grind to Powder: Once cooled, add the roasted seeds to a high-speed blender or food processor and pulse until a fine powder forms.
Add Sea Salt: Add a pinch of high-quality sea salt to enhance flavor and help preserve the butter naturally.
Blend into Butter: Continue blending until the mixture starts to form a paste. Take breaks between blending cycles to prevent the machine from overheating and to keep the seeds from getting too warm, which can degrade their healthy fats.
Incorporate Extra Virgin Olive Oil: Drizzle in a small amount of extra virgin olive oil—just enough to reach your desired consistency. Blend again until smooth and creamy.
Storage:
Store your homemade pumpkin seed butter in an airtight jar in the refrigerator. It stays fresh for up to 2–3 weeks.

1. Soak the seeds first—don’t skip this step
Pumpkin seeds contain phytic acid, which binds minerals like iron, zinc, magnesium, and calcium, preventing your body from absorbing them. By soaking seeds in water (ideally 6–12 hours), you activate an enzyme called phytase that breaks down phytic acid, improving mineral absorption.
2. Don’t use raw (unsoaked) seeds
Using unsoaked seeds means the phytic acid remains intact. This makes it harder for your body to use the minerals. Soaked seeds, on the other hand, release these minerals, making the seed butter more nutritious.
3. Avoid high-heat roasting
High temperatures can destroy phytase, which you just activated through soaking, and reduce antioxidant content. Instead, roast seeds lightly—around 150 °C (300 °F) for about 20–30 minutes—just enough to release their oils, without browning or burning them.
4. Pulse the blender—don’t run it continuously
Continuous blending generates heat, which can degrade nutrients and enzymes and even alter the flavor. Instead, process in short bursts: blend for a few seconds, stop, scrape down the sides, then blend again. Repeat until the butter reaches the desired creamy texture.
5. Add olive oil—don’t skip healthy fat balance
Pumpkin seeds are rich in omega‑6 fats. If not balanced with omega‑3s, this can promote inflammation. Adding a small amount of olive oil (which has omega‑9 and helps balance the fats) ensures a healthier fat profile and improves texture and flavor.

Fatty Acid Composition of Pumpkin Seeds
Pumpkin seeds are very high in fat (about 14 g per 1‑oz or 28 g shelled serving), the vast majority of which is unsaturated. In fact, *linoleic acid* (18:2 ω-6) is the dominant fatty acid. Nutrient databases report roughly **20.7 g** of linoleic acid and only **0.12 g** of α‑linolenic acid (18:3 ω-3) per 100 g of pumpkin seeds. Thus the ω-6:ω-3 ratio in plain pumpkin seed is extremely high (on the order of 150–200:1 by weight). Pumpkin seed oil studies likewise find \~30–47% linoleic acid and \~10–44% oleic acid (ω-9). In practical terms, a 1‑ounce serving contains about **5.8 g ω-6** (linoleic) and only trace ω-3 (ALA).
Importantly, pumpkin seeds also supply antioxidant micronutrients. They are rich in vitamin E (tocopherols), selenium, and carotenoids, which have anti-oxidant and anti-inflammatory effects. For example, one nutrition review notes that pumpkin seeds contain many antioxidant compounds (vitamin E, phenolics and carotenoids) that can protect against oxidative stress. These compounds may counteract some inflammatory triggers. Still, the *fatty acid profile* is overwhelmingly ω-6. By comparison, typical western diets already average an ω-6:ω-3 intake of \~20:1 (versus an ancestral \~4:1). Thus pumpkin seeds alone would further skew this ratio unless balanced by omega-3 sources.
## Omega-6, Omega-3 and Inflammation
Linoleic acid (ω-6) is an **essential** PUFA but can be metabolized into arachidonic acid and pro-inflammatory eicosanoids. Modern studies note that omega-3 PUFAs tend to **resolve inflammation** while omega-6 PUFAs tend to **promote** it. For example, one recent review summarizes that “omega-3s are utilized by the body to resolve and lower inflammation, whereas omega-6 … are primarily used for increasing inflammation”. In cellular studies, linoleic acid markedly boosted inflammatory signals: in one experiment, smooth muscle cells exposed to linoleic acid secreted **9-fold more IL-8** (a pro-inflammatory chemokine), whereas exposure to oleic acid (ω-9 monounsaturated) did not increase IL-8 at all. Linoleic acid also upregulated arachidonic-acid metabolites (e.g. prostaglandins, leukotrienes) via LOX/COX pathways. Thus in susceptible tissues (e.g. inflamed gut), excess linoleic acid can heighten inflammation.
However, evidence from diet studies is mixed. Leading health authorities (AHA/Harvard) emphasize that omega-6 fats from foods like seed oils and nuts are **heart-healthy** and **not inherently pro-inflammatory**. A major AHA advisory found that increasing dietary ω-6 (linoleic acid) did *not* raise inflammatory markers; in fact, replacing saturated fat with ω-6 PUFA lowered heart disease risk without boosting inflammation. Harvard Health likewise notes that omega-6 fats (from seeds, nuts, oils) “lower harmful LDL and boost protective HDL” and that reducing the ω-6:ω-3 ratio should come from *adding* ω-3, not *cutting* ω-6. In practice, most Americans get far more ω-6 than ω-3 (often 10–20:1), so experts recommend boosting ω-3 intake.
In summary, high ω-6 intake may contribute to a pro-inflammatory milieu, but foods like pumpkin seeds also contain antioxidants and MUFAs (oleic acid) which mitigate some risk. Pumpkin seed oil, for instance, contains about 33–47% linoleic and 32–44% oleic acid. Oleic acid has neutral or even anti-inflammatory effects (it did not trigger IL-8 and even modestly **reduced CRP** in human trials). So eating pumpkin seeds within a diverse diet is not guaranteed to *cause* inflammation, but the extreme ω-6:ω-3 ratio means one should consciously balance it with ω-3 sources to avoid exacerbating inflammation.
## Balancing With Omega-3 Oils and MUFAs
To improve the fatty acid balance of pumpkin seed butter, one can **blend in omega-3–rich and monounsaturated oils**. The goal is to raise ω-3 content and add MUFA, lowering the overall ω-6:ω-3 ratio. Sources of plant ω-3 (alpha-linolenic acid, ALA) include flaxseed oil, chia seeds, walnuts, and hemp oil. Flaxseed oil is especially rich (≈53% ALA), so even a small addition significantly boosts ω-3. Marine oils (fish, algae) supply EPA/DHA (long-chain ω-3) which are anti-inflammatory. **Monounsaturated oils** like extra-virgin olive oil are low in polyunsaturates and high in oleic acid, which is heart-healthy and inherently non-inflammatory. For example, adding olive oil increases MUFAs and slightly dilutes the ω-6 fraction; plus, olive oil brings antioxidants (oleocanthal, phenolics) that reduce inflammation.
In practical terms, blending roughly **5–15% flaxseed oil by weight** into the seed butter can dramatically improve the ratio. For instance, a simple calculation shows: 100 g pumpkin seeds (\~20.7 g ω-6, 0.12 g ω-3) plus 10 g flax oil (≈5.3 g ALA, 1.8 g LA) yields \~19.5 g ω-6 and 5.4 g ω-3 – a ratio of \~4:1. Even mixing in as little as 6–10% flax oil (with a bit of olive oil for texture) can shift the ratio below 10:1. Alternatively, sprinkling ground flax or chia seeds into the butter has a similar effect. Adding fish oil capsules (or algae oil) can supply EPA/DHA, but note the strong flavor and oxidation risk; if used, keep amounts small and store the butter tightly sealed in the fridge. Overall, the *AHA and dietary guidelines* suggest improving ω-6:ω-3 balance by **adding** ω-3 foods, not by eliminating ω-6 foods. Thus enriching pumpkin seed butter with flax oil, fish oil, or chia is a sound strategy.
By blending these ingredients, you create a pumpkin seed butter with a **more favorable ω-6:ω-3 balance**, leveraging healthy fats from flax, fish, or olive oil. Such a formulation still provides the benefits of pumpkin seeds (magnesium, zinc, protein, phytosterols) but mitigates the pro-inflammatory potential of pure omega-6 fat. The scientific rationale is that increasing anti-inflammatory ω-3 PUFAs and MUFAs shifts the eicosanoid balance toward resolving inflammation. This approach aligns with nutrition experts’ advice to “add more ω-3, not less ω-6” and to consume unsaturated fats (including ω-6) in place of saturated fats.
