Gluten-Free Rolled Oats | Whole Grain

When you’re shopping for oats with food allergies in mind, the facility matters as much as the ingredient label. Gerbs Traditional Rolled Oats and Instant Whole Grain Oats are produced exclusively in our family-owned and operated facility in Johnston, Rhode Island, a dedicated allergen-free environment free from the 14 most common allergens. No shared equipment. No co-packers. No shortcuts.

Rolled oats have been a breakfast staple for generations, but most commercial oats carry a very real cross-contamination risk because conventional oat processing facilities handle wheat, barley, and rye on the same lines. At Gerbs, that risk is eliminated by design. Our oats are processed on dedicated equipment by trained staff who understand what allergen-free truly means, not just a label claim but an operational commitment.

Whether you’re making a simple bowl of oatmeal, overnight oats, baked oatmeal, granola, or blending oats into flour for allergen-free baking, Gerbs rolled oats deliver the clean, nutty flavor and reliable texture that experienced allergy-aware cooks count on. The Gerbs Guarantee means every bag leaving our facility meets the same standard: pure oats, nothing else, sourced and processed with complete traceability.

For families managing celiac disease, gluten sensitivity, or multiple food allergies, finding an oat you can trust is not a minor convenience, it is a prerequisite for a safe and varied diet. Gerbs exists to make that search shorter.

Rolled oats, also called old-fashioned oats, are whole oat groats that have been steamed and then pressed flat with rollers. The steaming partially cooks the grain and stabilizes the natural oils, giving rolled oats a longer shelf life and faster cook time than whole groats. The result is a flat, oval flake that cooks in about 5 minutes on the stovetop and retains more texture than quick oats or instant oats.

Rolled oats are one of the most nutritionally dense whole grains available, a meaningful source of beta-glucan soluble fiber, protein, manganese, phosphorus, and iron. They are the base ingredient for oatmeal, granola, oat-based energy bars, overnight oats, and oat flour when blended. Gerbs also offers Instant Whole Grain Oats for faster preparation, thinner-cut for quicker cooking while retaining the whole grain profile.

Beta-Glucan Soluble Fiber for Heart Health

Rolled oats are one of the richest food sources of beta-glucan, a soluble fiber that has been extensively studied for its role in supporting healthy cholesterol levels already within the normal range. A standard ½ cup dry serving of rolled oats provides approximately 2g of beta-glucan. Research published by the Mayo Clinic indicates that beta-glucan may support healthy cholesterol levels by forming a viscous gel in the digestive tract that binds to cholesterol-containing bile acids and reduces their reabsorption. Oat beta-glucan has been recognized for decades as one of the most studied dietary fibers for supporting healthy cholesterol levels.

Sustained Energy from Complex Carbohydrates

Rolled oats are a source of complex carbohydrates with a lower glycemic index than refined grains. The combination of starch and soluble fiber slows glucose absorption, supporting more gradual and sustained energy release compared to processed breakfast foods. This makes oats a reliable morning food for people seeking longer satiety and stable energy.

Plant-Based Protein

A ½ cup dry serving of rolled oats contains approximately 5g of protein, making them one of the more protein-dense whole grains available. Oat protein contains all essential amino acids, though lysine is the limiting amino acid. Paired with other protein sources, oats contribute meaningfully to daily protein intake without animal products.

Manganese and Phosphorus for Bone and Metabolic Function

Rolled oats are a significant source of manganese, a trace mineral that plays a role in bone formation, wound healing, and amino acid metabolism, providing over 60% of the Daily Value per serving according to USDA nutritional data. They also supply phosphorus, important for bone mineralization and cellular energy processes.

Iron for Oxygen Transport

A serving of rolled oats provides approximately 2mg of iron, contributing to the daily requirement for this essential mineral. Iron is a key component of hemoglobin, the protein in red blood cells responsible for transporting oxygen throughout the body. Plant-based iron (non-heme iron) is less readily absorbed than heme iron, but pairing oats with a vitamin C-containing food may support absorption according to NIH guidance.

As with all foods, individual results may vary. Gerbs makes no medical claims.

Rolled oats have a mild, clean, slightly nutty flavor with a hint of natural sweetness from the grain. The texture after cooking is creamy and soft with some intact flake structure, more body than quick oats, less chew than steel-cut. Raw, they are dry and starchy with a mild grain aroma. Toasted in granola, they develop a deeper, nuttier note. The neutral flavor makes them highly compatible with both sweet and savory preparations.

Organic Rolled Oats.

Stovetop (Classic Method)

Combine 1 part rolled oats with 2 parts water or milk alternative in a saucepan. Bring to a light boil over medium heat, then reduce to a simmer. Cook for approximately 5 minutes, stirring occasionally, until oats reach your preferred consistency. Remove from heat and let stand 1-2 minutes before serving. A pinch of salt enhances the natural grain flavor. The 1:2 ratio produces a creamy, pourable consistency; reduce water slightly for thicker oatmeal.

Overnight Oats (No-Cook)

Combine 1 part rolled oats with 1.5 parts milk alternative or water in a jar or container. Stir briefly, seal, and refrigerate overnight (minimum 6 hours). The oats absorb the liquid and soften to a thick, creamy texture without any cooking. Top with fruit, nut-free granola, seeds, or cacao nibs before serving. Overnight oats keep refrigerated for up to 3 days.

Microwave

Combine ½ cup rolled oats and 1 cup water or milk alternative in a microwave-safe bowl (use a large bowl, oats expand during cooking). Microwave on high for 90 seconds to 2 minutes, stopping to stir once at the midpoint. Let stand 1 minute before serving. Watch carefully to prevent boilover.

Baked Oatmeal

Mix 3 cups rolled oats with 2 cups milk alternative, 2 eggs (or flax eggs), ¼ cup maple syrup, 1 tsp baking powder, and desired fruit or mix-ins. Pour into a greased 9×13 baking pan and bake at 375°F for 35-40 minutes until set and lightly golden. Slice into squares and serve warm, or refrigerate and reheat portions throughout the week.

Oat Flour (DIY)

Process rolled oats in a high-speed blender or food processor until a fine, uniform powder forms, approximately 60 seconds. Sift to remove larger pieces. Use as a gluten-free flour component in pancakes, cookies, and quick breads. Note that oat flour does not contain gluten and behaves differently than wheat flour in yeast-based recipes.

Store in an airtight container in a cool, dry location away from direct sunlight and heat. Properly stored, rolled oats and oat groats maintain quality for 12-18 months. For longer-term storage, freeze in sealed, moisture-proof bags or containers, oats freeze well and can be used directly from frozen in most applications. Do not store near strong-smelling foods, as oats can absorb ambient odors.
