Measure your ingredients and set them out. Having everything pre-measured (mise en place) makes the short cooking window for steel-cut oats stress-free and prevents overcooking or scorching.

Toast the sliced almonds: place a small dry skillet over medium heat, add the sliced almonds and toast, stirring constantly, for 2–3 minutes until fragrant and lightly golden. Remove from pan and set aside. Toasting releases the oils and intensifies the nutty flavor and adds crunch that contrasts the soft oats.

Bring the liquid to a simmer: in a medium heavy-bottomed saucepan combine 1 1/4 cups (300 ml) water and 1 cup (240 ml) unsweetened almond milk with a pinch of salt. Warm over medium heat until small bubbles appear at the edge — do not boil vigorously. Warming the liquid first prevents the oats from clumping and helps them hydrate evenly.

Add the steel-cut oats and cinnamon: stir in the 3/4 cup (90 g) steel-cut oats and the pinch (1/8 tsp) ground cinnamon. Reduce heat to low so the mixture maintains a gentle simmer. A low, steady simmer allows the oats to soften gradually and develop a creamy texture without sticking or becoming gluey.

Slow-simmer, stirring occasionally: cook uncovered for 20–25 minutes, stirring every 3–5 minutes and scraping the bottom with a wooden spoon to prevent sticking. If the pot looks too dry, add a tablespoon or two of hot water. The occasional stirring helps release oat starches for a naturally creamy porridge; scraping prevents hot spots and scorching.

Finish with chia seeds and sweetener: after 20–25 minutes the oats should be tender but still have a pleasant bite (al dente). Remove from heat and immediately stir in 1 tablespoon chia seeds and 1 teaspoon honey or maple syrup. Chia seeds absorb some liquid and give the porridge a silkier mouthfeel while adding omegas and fiber; adding them at the end prevents them from becoming gummy.

Fold in berries: gently fold about 3/4 of the mixed berries into the oats to warm them slightly; reserve the rest for topping. Warming the fruit releases juices that lightly sweeten the oats without breaking down all the berry texture.

Toast a quick berry pan-reduction (optional): if you want an elevated touch, in the almond-toasting skillet add the reserved berries and a small splash (1 teaspoon) of water and warm over medium-low for 1–2 minutes until they release a glossy sauce. Spoon this over the bowls for bright color and concentrated berry flavor.

Plate and garnish: divide the oats between two bowls. Top each with the remaining fresh berries, the toasted sliced almonds, and an additional light dusting of cinnamon if you like. A final drizzle of honey or maple adds shine and a whisper more sweetness.

Serve immediately: serve while warm. Steel-cut oats will thicken as they cool; if reheating later, add a splash of almond milk and gently warm to loosen the texture.
