Mission Revival Sourdough Toast with Avocado & Scallion Oil
Rustic, tangy sourdough slices toasted to a golden crisp and topped with creamy, in-season Hass avocado. This dish is elevated by a vibrant, cold-pressed scallion oil made with extra-virgin olive oil, delivering a bright, savory punch without any seed oils or refined additives.
A little context
Rooted in the California Mission Revival aesthetic, this dish celebrates the state's abundance of avocados and artisanal breads, stripping away the commercial seed-oil spreads and sugar-laden jams often found in modern interpretations. We honor the tradition by using only cold-pressed extra-virgin olive oil and grass-fed or wild-caught fats where applicable, ensuring every bite supports longevity rather than inflammation.
The longevity story
This recipe leverages the fermentation of sourdough to lower the glycemic impact of the grain and improve mineral bioavailability. The Hass avocado provides monounsaturated fats and fiber, while the extra-virgin olive oil in the scallion oil delivers oleocanthal, a potent polyphenol with anti-inflammatory properties comparable to ibuprofen. Scallions contribute prebiotic inulin and quercetin, supporting gut microbiome diversity and cardiovascular health.
Method
- 01
Prepare the Scallion Oil
Combine the chopped scallion whites and light greens with the extra-virgin olive oil in your high-speed blender. Blend on high for 60 seconds until the mixture is completely emulsified and bright green. Taste and season lightly with a pinch of sea salt if desired. Set aside.
- 02
Toast the Sourdough
Heat your cast-iron skillet over medium-high heat. Once hot, place the sourdough slices directly onto the dry skillet (no oil needed). Toast for 2-3 minutes per side until deep golden brown and crisp. Remove and immediately rub one side of each slice with a cut garlic clove for subtle aroma, optional.
- 03
Mash the Avocado
While the bread toasts, mash the avocados in a small bowl with the fresh lemon juice and half of the flaky sea salt. Do not over-mash; you want a rustic texture with small chunks remaining.
- 04
Assemble the Toasts
Spoon the mashed avocado generously onto the warm sourdough slices, spreading to the edges. Drizzle the scallion oil liberally over the top, ensuring the bread absorbs some of the fat.
- 05
Finish and Serve
Top with the remaining flaky sea salt and fresh microgreens or cilantro. Serve immediately while the bread is still warm and the avocado is creamy.
Pro tips
- ✦Sourcing: Look for avocados that are heavy for their size with skin that is dark green to black; if the skin is bright green, they are likely under-ripe.
- ✦Freshness: Make the scallion oil no more than 24 hours in advance to preserve the chlorophyll and prevent oxidation; store in the fridge.
- ✦Texture: For the best crunch, use sourdough that is at least a day old; fresh bread tends to steam rather than crisp in the skillet.
- ✦Flavor: If you have access to local honey, a single tiny drop (1g) can be whisked into the scallion oil to round out the sharp bite, though it is not necessary.

Substitutions
- extra-virgin olive oil → avocado oil or cold-pressed macadamia nut oil (maintains high smoke point and monounsaturated fat profile)
- sprouted whole-grain sourdough → gluten-free sprouted grain bread or almond flour keto bread (ensure the substitute is free of seed oils and added sugars)
- scallions → green garlic or ramps (in season) (provides a more intense, allium-forward flavor profile)
Storage
Scallion oil keeps in an airtight glass jar in the fridge for up to 5 days. Avocado toast is best eaten fresh; if prepping ahead, store mashed avocado with a lemon wedge on top and wrap tightly in beeswax wrap to minimize browning.
What to serve with it
- Hot green tea (sencha or matcha) for catechins
- Sparkling water with a wedge of lime and fresh mint
- Cold-pressed vegetable juice with celery and cucumber
- Dry Pinot Noir (optional, for evening)
FAQ
Can I heat the scallion oil?+
No. Heating the scallion oil will destroy the delicate polyphenols in the olive oil and turn the scallions bitter. Always add the oil cold as a finishing drizzle.
Is this truly Blueprint-aligned?+
Yes, provided you use a sprouted grain bread with no added sugars or seed oils, and strictly use EVOO or avocado oil instead of industrial seed oils.
