Steps
Before you start
- Take the eggs and buttermilk out of the fridge 30 minutes ahead so the batter mixes smoothly and the muffins rise evenly.
- Harissa brands vary widely in heat and saltiness. Taste a little first; if yours is very hot, start with 2 tablespoons (35 g).
- Grate the cheddar from a block rather than using pre-shredded cheese. Pre-shredded cheese is coated in starch and melts less well.
- Total time is about 57 minutes, including a 10-minute cool-down.
Heat oven, prep tinOven 400°F / 205°C
- Position a rack in the center of the oven and preheat to 400°F (200°C).
- Line a 12-cup standard muffin tin with paper liners, or brush each cup generously with oil.

Ready when: Oven reaches 400°F (200°C) and the tin is lined or greased in every cup.
Tip: Liners can stick to low-fat muffins; lightly greasing the liners helps them peel away cleanly.
Prep peppers and cheese
- Drain the roasted red peppers, spread them on a double layer of paper towels, and press with more towels until no wet sheen remains.
- Chop into ¼-inch (6 mm) pieces.
- Grate the cheddar, then set aside ¼ cup (30 g) for the topping.
- Slice the scallions.

Ready when: Peppers look matte and dry, not glossy or dripping.
Tip: Wet peppers add excess moisture and make gummy streaks in the crumb, so dry them thoroughly.
Whisk dry ingredients
- In a large bowl, whisk together the flour, baking powder, baking soda, salt, cumin, and caraway for about 30 seconds until the spices are evenly distributed.

Ready when: The mixture is a uniform pale tan with no streaks of spice or clumps of leavening.
Whisk wet ingredients
- In a medium bowl, whisk the eggs until the yolks are broken up.
- Add the buttermilk, olive oil, and harissa, and whisk for about 1 minute until the harissa is fully dissolved and the liquid is a uniform orange-red.

Ready when: No lumps of harissa remain and the mixture is evenly colored.
Tip: If the buttermilk is cold, the oil can clump. Bring it to room temperature first.
Combine batter
- Pour the wet mixture into the dry ingredients.
- Fold with a rubber spatula for 10 to 12 strokes, just until most of the flour disappears.
- Add the peppers, 1½ cups (170 g) cheddar, and scallions, then fold 4 to 5 more times until just distributed.

Ready when: The batter is thick and lumpy with a few small flour streaks. It should not be smooth.
Tip: Overmixing develops gluten and makes tough, tunneled muffins. Stop while a few streaks remain.
Fill and top
- Divide the batter among the 12 cups using a large scoop or spoon, filling each about ¾ full (roughly ⅓ cup / 80 ml each).
- Sprinkle the reserved ¼ cup (30 g) cheddar and the sesame seeds evenly over the tops.

Ready when: Batter mounds slightly above the rim with no empty cups.
Tip: Work quickly after mixing; baking powder and baking soda start reacting as soon as they meet the buttermilk.
Bake the muffinsOven 400°F / 205°C
- Bake at 400°F (200°C) for 20 to 22 minutes, rotating the tin front to back after 12 minutes, until the tops are deep golden and the cheese is browned in spots.

Ready when: A toothpick inserted into the center comes out clean (a smear of melted cheese is fine), the tops spring back when pressed, and the center reads about 205°F (96°C).
Tip: A toothpick that hits a pocket of cheese or pepper can look wet. Test a second spot to be sure.
Cool and release
- Let the muffins rest in the tin for 5 minutes so they set and the melted cheese firms up.
- Run a thin knife around any stuck edges, then move the muffins to a wire rack and cool at least 5 minutes more before serving warm.

Ready when: Muffins lift out cleanly and the bottoms feel dry, not damp.
Tip: Don't leave them in the tin longer than 10 minutes, or steam will make the bottoms soggy.
Good to know
Tips
- Pat the roasted peppers truly dry; this is the biggest factor in a light, evenly baked crumb.
- For more heat, add 1 to 2 tsp extra harissa to the wet mix or serve with a dab of harissa-spiked butter. Don't add much more to the batter, which can make it dense.
- The 400°F (200°C) oven gives the muffins a quick burst of rise and tall domed tops, so don't open the door in the first 12 minutes.
- Serve warm with a smear of labneh, cream cheese, or butter and a fried egg for a savory breakfast.
Make ahead
"Mix the dry ingredients and the wet ingredients separately up to 12 hours ahead; cover the wet mixture and refrigerate it, then bring it to room temperature for 30 minutes. Prep the peppers, cheese, and scallions the day before and refrigerate. Combine and bake just before serving. Fully baked muffins also freeze well (see storage)."
Storage & reheating
"Room temperature: up to 8 hours in a loosely covered container; because of the cheese, refrigerate after that. Fridge: up to 4 days in an airtight container. Freezer: up to 3 months, wrapped individually in plastic and stored in a freezer bag. Reheat refrigerated muffins at 325°F (160°C) for 8 to 10 minutes, or frozen ones for 15 to 18 minutes, until warm in the center. A microwave works in a pinch: 20 to 30 seconds for refrigerated, 45 to 60 seconds for thawed."
Substitutions
- buttermilk → 1 cup (240 ml) whole milk plus 1 tbsp lemon juice or white vinegar, stirred and left 5 minutes, or plain whole-milk yogurt thinned with a splash of milk. Gives the same tang and activates the baking soda; the texture will be very close.
- harissa paste → 2 tbsp (35 g) tomato paste plus 1 tsp smoked paprika and ½ tsp cayenne pepper. Approximates the smoky, chile-forward flavor; adjust cayenne to taste.
- sharp cheddar cheese → Gruyère, Monterey Jack, or Gouda in the same weight. Gruyère gives a nuttier flavor; Monterey Jack is milder and melts very smoothly.
- extra-virgin olive oil → Melted unsalted butter (⅓ cup / 75 g) or a neutral oil. Butter gives a richer flavor; neutral oil lets the harissa and peppers stand out.
